The problem of isosceles-triangle diagonal vertical
A triangle does not have a diagonal line. In an isosceles-shaped triangle, if it is an isosceles-right triangle, then the two waists are vertical to each other; if it is a general isosceles-shaped triangle, then the top angle bisecting line vertically bisects the base.

Cube Diagonal vertical picture
The diagonal lines of the cube are vertical to the two red faces in the diagram (let's assume that in a particular cube example diagram, they are labeled as faces AA1D1 and C1DB). This vertical relationship could be proved by setting the side length of the cube to be 1, finding A1B = 2 in the square AWB1A1, finding A1C = 3 in the triangle A1BG according to the Pythagorean theorem, and then finding the vertical line of the triangular pyramid A1 -AWB1D1 according to the equal volume method. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Diagonal composition photography
Diagonal composition is a photography composition method. It has the following characteristics and application methods: ** I. The definition of diagonal line composition ** 1. ** Line Form ** - The main image in the picture was presented as a slanted line. This kind of inclination was not necessarily slanted to the extent of a diagonal line, but it could also be slightly slanted, or almost horizontal but a little slanted. - An oblique line was not necessarily formed by an actual line. It could also be formed by two points. For example, if there was an object in the upper left corner and an object in the lower right corner, if there was a potential connection between the two, the brain would imagine that there was a line between them. This was also considered an oblique line composition. 2. ** Different from other compositions ** - Compared to the tranquility of the horizontal line composition, the diagonal line composition was dynamic, lively, and gave people a sense of infinite vitality. Compared with the vertical line composition, the vertical line composition emphasized seriousness and tranquility, while the diagonal line composition emphasized dynamic effects. ** 2. Character and emotional expression of diagonal composition ** 1. ** Dynamic and energetic ** - It was more dynamic than the horizontal and vertical lines. It was like a pencil that was standing on the table and falling down. It could bring about kinetic energy, showing a lively, young, energetic, innovative, hopeful, powerful, sharp, and so on. - For example, when shooting plants, the diagonal composition could be used to show the state of the plants growing upwards. When there was a breeze blowing, the diagonal composition could increase the movement of the picture to make it lively and interesting, and the plants looked cute and cute. 2. ** Adaptability of the theme ** - The emotion of the slash had to be compatible with the theme. If the theme needs to reflect the dynamic, dynamic, or unstable emotions, you can use diagonal composition; if the theme is quiet and stable, it may not be appropriate to use diagonal composition, but there are special circumstances, such as adding diagonal elements to create unexpected effects in quiet scenes to avoid excessive boredom. ** 3. Shooting Techniques for Diagonal Line Composing ** 1. ** Searching for slash elements ** - Directly look for diagonal elements in the shooting scene, such as the handrails in life, the wires in the sky, etc., which are originally horizontal lines. When you approach one end and use an upshot or an upshot, they will act as diagonal lines in the picture. 2. ** Create a slash effect ** - You can rotate or tilt the camera to turn the original horizontal and vertical lines into a diagonal line. This method is generally used when shooting from above or below. However, it was rare to tilt the camera when shooting straight ahead because it might make the audience feel unstable. However, in documentary photography or news photography, if you wanted to express a sense of panic, you could tilt the camera slightly to make the horizon crooked to serve the theme. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to level the diagonal
If the leveling of the indoor wall involves diagonal leveling, the base layer interface must be treated first. The dust, dirt, oil stains, etc. on the surface of the base layer must be cleaned up. The gray joints of the building blocks must be treated in advance. The uneven parts between different matrixes must be polished and repaired in advance. The vertical deviation and smoothness of the wall must be checked with a hanging wire. After the floating soil on the wall surface is cleaned, it must be watered repeatedly.(The watering order is from top to bottom. The watering amount should be 8 - 10mm deep into the building blocks and should be carried out one day before the plaster. If the wall is still dry during the plaster, you can spray water again, but there is no floating water on the wall during the plaster.) Then, set out and mark to determine the thickness of the plaster (the thickness of the inner wall plaster should be about 20mm, and at least not less than 7mm). Stick the plaster cake first and then paste the plaster cake again (the distance between the plaster cakes should not be more than 1500mm and 30mm from the ground). When the plaster cake is dry, spread 100mm wide mortar between the plaster cakes and scrape it flat with a scraper bar (the thickness is the same as the plaster cake). After the mortar bar is slightly dry, the bottom layer of the plaster shall be plastered. Through these operations, the straightness and smoothness of the wall can be ensured, and the leveling in the diagonal direction can be indirectly realized. If the foundation cushion is leveled and repaired with a large height difference in the diagonal direction during construction, for example, when the cushion has a size of 3500* 3500mm and the height difference in the diagonal direction reaches 10cm, the surface of the cushion can be cleaned, and a new layer of C15 concrete can be placed on it. Leveling shall be based on the highest point of the original cushion, and the difference between the upper surface of the cushion and the designed elevation shall be measured (estimated to be no more than 10cm). Then continue to build the foundation. When doing the foundation, the height of the cushion layer will be deducted from the height of the upper step of the foundation, and the cross section of the upper step will be enlarged (if there is reinforcement in this part, the reinforcement will be changed accordingly). The size of each side can be the same as the height of the foundation cushion layer, so as to ensure that the elevation of the top surface of the foundation remains unchanged. If there is a problem with the smoothness of the floor tiles, but the master thinks that it is enough as long as the corners are flat, in this case, if the floor tiles are to be completely leveled, the master should generally pick up the floor tiles and lay them again when the cement layer has not completely shrunk and solidified. If the cement has solidified, the bricks may damage the floor tiles next to it. This situation is more complicated. There is no clear conventional treatment method. Special measures may need to be taken according to the actual situation, such as local adjustment of the height of the floor tiles. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Diagonal angle of the cube
The two diagonal lines of the cube are in the same plane. Let the length of the cube be a, and the diagonal line of the cube be (<sqrt{2}a>>), the angle between the face diagonal and the body diagonal.(\alpha = \arctan\sqrt{2}\), get (alpha = 54.7356) degrees, the diagonal of the two bodies meet at a point to form two isosceles-shaped triangle, so the top angle of the isosceles-shaped triangle is the top angle.(The angle of the diagonal line)(<beta>= 180 - 2 <alpha>= 70.5288>) degrees; The angle formed by the diagonal and the bottom of the cube is <A>,<A>=<frac{1}><sqrt{3}>>=<approx0.5774>>,<A>=<arcsin0.5774>=<approx35.27 ^{<circ}>(The final result is kept in two decimals). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to express the diagonal of a square
If the side length of a square is a, according to the Pythagorean theorem, its diagonal length is d = a sqrt {2}, which is the side length multiplied by the square length. It can also be expressed as the square root of the diagonal length is 2a^{2}. The two diagonal lines of a square are equal and bisect each other vertically. Each diagonal line bisects a set of diagonal lines. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
matlab matrix diagonal operation
In MATLAB, there were many situations for matrix diagonal operations: 1. ** Extracting Diagonal Elements ** - To extract the main diagonal elements of matrix A, you can use the diag(A) function, which produces a column. - If you want to extract the elements of the kth diagonal of matrix A, you can use the diag(A,k) function, which will also produce a column matrix.(Diagonal lines of the matrix: parallel to the main diagonal, up are the 1st, 2nd, all the way to the nth diagonal, down are the-1st,-2nd, all the way to the- n diagonal, and the main diagonal is the 0th diagonal). 2. ** Construct Diagonal Matrix ** - If there is a V, to construct a diagonal matrix with V as the main diagonal element, you can use the diag(V) function. - If you want to construct a diagonal matrix with the kth diagonal element of the V, you can use the diag(V,k) function. 3. ** Zero the diagonal of the matrix **: For example, first generate a test matrix A = magic(5). To set the diagonal to zero, you can first extract the diagonal elements, assign them to zero, and then reconstruct the matrix (The reference does not provide a function to directly set the diagonal to zero. Here is an idea). Assuming that A is a square matrix, the following steps are used: - extracting the main diagonal element d = diag(A); - assign the element in d to zero; - Then construct the matrix A = diag(d)+A - diag(diag(A)). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The diagonal length of a cuboid is 13cm
He only knew that the diagonal length of the cuboid was 13cm. He could not get more specific information about the cuboid, such as its length, width, height, surface area, or volume. He needed other conditions, such as the proportional relationship between length, width, and height, or additional side length values, to further calculate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
