No, not at all the same thing! While an equilateral triangle does, by definition, have equal sides (of any length) AND equal angles (always 60º), there are a myriad of non-equilateral (aka scalene) 60º triangles. Surely you've heard of a 30º-60º-90º right triangle?
The pattern that calls it a '60º equilateral triangle' is far more accurate than the one calling it merely a '60º triangle', though the latter probably just figured people would "assume" that's what was intended...as you all did.

I have three 60* triangles and they are all different!! Weird.... I only use the one that matches the drawing in EB's 25th anniversary book.
