0 A diagonal line is straight and sloping, not horizontal or vertical, for example joining two opposite corners of a square or other flat shape with four sides: --
1 a straight line that joins two opposite corners of a four-sided flat shape, such as a square --
2 (of a line) straight and sloping, so that it is neither horizontal nor vertical: --
A so-called crossed rectangle is a crossed (self-intersecting) quadrilateral which consists of two opposite sides of a rectangle along with the two diagonals.
As with the 208 field, cone contrasts calculated with respect to the perceived background appear closer to the diagonal.
Find the centers of mass of these two rectangles by drawing the diagonals.
The infill between the top and bottom rails and the vertical supports is a series of interlocking diagonals, although rectilinear designs exist as well.
The pentagram map takes a given polygon, finds the intersections of the shortest diagonals of the polygon, and constructs a new polygon from these intersections.
Therefore, the sum of the diagonals is equal to the perimeter of the quadrilateral formed.
Obviously, matrix is not diagonal in general but it is often assumed to be diagonal in practice and takes damping ratios as its diagonal components.
The thick diagonal line separates the traditional orientations ofprocessual archaeology (left) from those of post-processual archaeology (right).
