Which regular polygons can be dissected into isosceles triangles by non-intersecting diagonals?

(In reply to re(2): Equilateral triangle are certainly isosceles. by Jer)

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!
