WebExample 2: The perimeter of an isosceles right triangle is 10 + 5√2. If the non-congruent side measures 5√2 units then, find the measure of the congruent sides. Solution: For a right isosceles triangle, the perimeter formula is given by 2x + l where x is the congruent side length and l is the length of the hypotenuse. Here, l = 5√2 units, Perimeter = 10 + 5√2 units WebThe formula h = ( √a2–b2/4) is used as a calculation tool to determine the altitude of an isosceles triangle.
