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

how many triangles are formed when any parallelogram and it diagonals are drawn
If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed
5 triangles are formed.

The equation is: 0.5*(n2-3n) = diagonals whereas n is the number of sides of the polygon

The three major diagonals in an ordinary hexagon do not intersect at the same point. Therefore, in such a hexagon, the diagonals form 111 triangles.
