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 Triangle: Definition, Properties, Types, Formulas
Right Triangle Definition Right triangle is a figure where one of the three angles measures 90° and the other two angles are acute that sums to 90°.

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!

Special right triangle - Wikipedia
Angle-based special right triangles are those involving some special relationship between the triangle's three angle measures. The angles of these triangles are such that the larger (right) angle, which is 90 degrees or π 2 radians, is equal to the sum of the other two angles.

Right Triangle -- from Wolfram MathWorld
A right triangle is a triangle with an angle of 90 degrees (pi/2 radians). The sides a, b, and c of such a triangle satisfy the Pythagorean theorem a^2+b^2=c^2, (1) where the largest side is conventionally denoted c and is called the hypotenuse.
