## What is an isosceles right angle triangle and how its area is calculated ?

An isosceles triangle is a triangle that has any two of its sides equal to each other. Also, the angles opposite these equal sides are equal. In an isosceles right-angle triangle, one angle is 90 degrees and the rest two angles are 45 degrees. Its area is calculated by the formula A = ½ × a2 where A is the area of the triangle and a is the length of equal side of an isosceles triangle.
