Download Octagon Number Of Triangles PNG. I shall give a proof to include all convex polygons with 5 or more sides in general, thus an octagon can be seen as 8 equal isosceles triangles with the apexes meeting at the centre of the octagon. The number of triangles created by drawing the diagonals from a given vertex.

Then the second vertex, going. Break the octagon into 8 congruent triangles. The idea is based on the fact that n'th triangular number can be written as sum of n natural numbers, that is n. Since the sum of internal angles in one triangle is 180°, it is concluded that 6 triangles, side by.
