|\ |_\ right-angled triangle
-- Every triangle, no matter what its shape or size, has three angles inside it that add up to 180 degrees. -- Whyen you say "regular right angled triangle", I hope you don't mean that all three of its sides are the same length ... that's what "regular" usually means in geometry. It's impossible for a right triangle to have all of its sides equal.
