Which regular polygons can be dissected into isosceles triangles by non-intersecting diagonals?
Does a hexagon count?
3 around the outside, and enclosed equilateral: equilaterals are also isosceles.
Question is: for this problem do we need "non-equilateral" isosceles?
I haven't had time to try to find a pattern but I think we need to know if a pattern fits. Maybe one pattern that includes equilateral and another pattern that does not.
