Radius of the incircle of a right triangle
Description
Right triangle or right-angled triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. The center of the incircle is called the triangle’s incenter. The radius of the incircle of a right triangle can be expressed in terms of legs and the hypotenuse of the right triangle.
