Interactive Polygons Interior Angles of … WebUse permutation and combinations to evaluate the required answer: We need to form triangles by joining the vertices of a hexagon. To form a triangle we require 3 vertices. So, from the given 6 vertices of a hexagon we can choose 3 vertices in C 3 6 ways. The number of triangles that can be formed = C 6 3.
7 triangles can be drawn in a nonagon. A nonagon can be split into triangles with the help of its diagonals that are drawn from its vertices. The number of triangles that are created by these diagonals, can be calculated with the formula: (n - 2), where n = the number of sides. In this case, n = 9. So, after … Meer weergeven A convex nonagon has the following properties. 1. A convex nonagon is one in which all the interior angles measure less than 180°. 2.
