Diagonal

Joins two nonadjacent sides of a polygon with a slanted or oblique direction from one corner to the other; their use in a square or rectangle produces two triangular shapes.

Diagonal

 

a dense fabric of twisted cotton or wool yarn. Diagonals are characterized by sharp ribs on the surface running at an angle of more than 45° to the selvage. The ribs are obtained by proper selection of the ratio of the density and thickness of the warp and woof, as well as by the special interweaving of threads. Diagonal is used for uniforms (from wool warp and cotton woof), coats, and jackets.


Diagonal

 

(1) The diagonal of a polygon is the line segment between two nonadjacent vertices. If the number of vertices of a polygon is n, then the number of diagonals is n(n -3)12.

(2) The diagonal of a polyhedron is the line segment between two vertices that do not lie on the same face.
