Which regular polygons can be dissected into isosceles triangles by non-intersecting diagonals?
(In reply to re(2): Equilateral triangle are certainly isosceles.
Wow! Didn't notice that!
I just put in the first 15 or so numbers and found A173786, which is what I was describing. How interesting that these two sequences are essentially identical. In fact, when I think about it, the fact seems perfectly simple.
I had a lot of fun on this one! Thanks Jer!
