Right triangle - Wikipedia
A right triangle or right-angled triangle, sometimes called an orthogonal triangle or rectangular triangle, is a triangle in which two sides are perpendicular, forming a right angle (1⁄4 turn or 90 degrees).

Right Triangles - Math is Fun
There are two types of right triangle: Isosceles right triangle. Scalene right triangle. The "3,4,5 Triangle" has a right angle in it. (Draw one if you ever need a right angle!) It has no equal sides so it is a scalene right triangle. And, like all triangles, the three angles always add up to 180°. Can a right triangle be equilateral? No!
