Equilateral triangle are certainly isosceles.

I'm amazed this has cropped up but I will serve as arbiter since it's my problem.

To be an isosceles triangle it must have two equal sides. An equilateral triangle dies have two equal sides. Which two? Any two!

Are we going to wonder if a square counts as a rectangle next?
