Pythagorus

I've not heard of a Pythagoras triangle. Pythagoras's theorum relates to right-angles triangles. They may be referred to as Pythagoras triangles, but I've never heard them so described.

Isosceles triangles (those with two equal sides) are named after the greek word for "equal legged". 

The only other triangle I know of is an equilateral triangle which, as its name suggests, has three sides of equal length.

I believe Euclid did some work on 3:4:5 triangles (where a triangle of side lengths (or factors of)  3, 4, and 5 units of length form a right-angled triangle.

He didn't however work out the "square of the hypoteneuse" rule attributed to Pythagorus.

I have heard of both Euclidean and Pythagorean triangles..

yes, I've heard the triangles adhering to Pythagorus' rule referred to as 'Pythagorus triangles' all throughout school/A-levels
