in an isosceles triangle the vertex angle measures 90 degrees and the length of each congruent leg is 5√2. whats the length of the base?

    Isn't the base the hypotenuse of a right-angled triangle?

    so h^2 = (5√2)^ + (5√2)^2
    = .......

    You should not need a calculator.

    h^2 = (5√2)^ + (5√2)^2
    = 50 + 50
    = 100
    h = √100 = 10
