Right-Angled Triangle

 A right triangle or right-angled triangle is

a triangle in which one angle is a right

angle (that is, a 90-degree angle).

 The side opposite the right angle is called the

hypotenuse (side c in the figure).

 Note: In a right triangle, one of the angles

measures is 90º and each one of the remaining

two angles is acute.
