Question

Choose the correct decomposition of the regular polygon into n−2 triangles.

Answer 1

The correct decomposition of a regular polygon into n−2 triangles is as follows:

1) Connect one vertex of the polygon to every other vertex, creating n-2 diagonals.
2) Each diagonal will form a triangle with two adjacent sides of the polygon.
3) Continue this process until all vertices have been connected, resulting in n-2 triangles.
4) Ensure that no diagonals intersect or overlap each other, as this would result in a non-convex polygon decomposition.
