## Maths keeps one mentally active.

How many triangles can be formed by joining the vertices of hexagon in two dimension. How many triangles can be drawn by joining the vertices of a decagon. For irregular Polygons total triangles. How many triangles are in a hexagon. So unless you specify that the polygon is convex or has some other property that guarantees non-collinearity of vertices, then this question has no answer.How many diagonals can be drawn by joining the vertices of an octagon.
