An isosceles triangle is a triangle having at least two congruent sides.
In a right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs.
Thus, c^2 = a^2 + b^2
Therefore, since a = b, or x = x, in your problem
8^2 = x^2 + x^2
Solve this equation for x for your answer
