Solve using permutations and combinations. Join up all diagonals of a convex n-gon, how many triangles can be formed on the plane. How many triangles are formed if we join all the vertices of a hexagon.

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. Will you create the city of your dreams. Then vertices can be joined with its centre of gravity centroid. How many triangles can be drawn by joining vertices of a regular hexagon an.
