Web9 feb. 2013 · A regular polygon has some number of sides (n), and its sides and diagonals form a certain number of triangles (t). For a triangle, n=3 and t=1. For a square, n=4. There are four triangles congruent to the one shown in orange, and four more like the one shown in light blue, so adding these gives t=8. For a pentagon, with n=5, there are five of ... WebA triangle is defined as a closed shape that has 3 sides, 3 angles, and 3 vertices. It is the simplest type of polygon. No vertices in a triangle are non-adjacent. It means that there are no line segments that can form diagonals. Therefore, the number of diagonals of a triangle = 0. In other words, there are no diagonals in a triangle.
