You can put this solution on YOUR website!
if one leg (a) in a 45°-45° right triangle has a length of 8, than the other leg (b) has a length of 8 too because it’s an isosceles triangle (both legs have the same length)
so, the length of a hypotenuse c is:
c%5E2=a%5E2%2Bb%5E2
c%5E2=8%5E2%2B8%5E2
c%5E2=64%2B64
c%5E2=2%2A64
c=sqrt%282%2A64%29
c=8%2Asqrt%282%29=>the length of a hypotenuse
