yes
The diagonals of a square for example divides it into 4 isosceles triangles
There are 8
The number of triangles formed by the diagonals of a 21 sided polygon is C(21,3) = 21x20x19/3x2x1 = 1,330.

It is: 8-2 = 6 triangles
how many triangles are formed when any parallelogram and it diagonals are drawn
5 triangles are formed.
If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed
10
The equation is: 0.5*(n2-3n) = diagonals whereas n is the number of sides of the polygon
6
1 triangle is formed.
