Which regular polygons can be dissected into isosceles triangles by non-intersecting diagonals?
The regular polygons that can be dissected into isosceles triangles by non-intersecting diagonals are those where the number of vertices (and, thus, the number of sides) of the polygon are in the form of any of the following, such that n and k are positive integers:
3·2
n,
4·2
n,
5·2
n, and
2
(2+n+k) + 2
