Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem, 82 + 62
= 62, which in this isosceles triangle becomes
32 + 12 = 22. By combining like terms, 262 = 22
Which final step will prove that the length of the
hypotenuse, c, is 2 times the length of each leg?
2
O Substitute values for a and cinto the original
Pythagorean theorem equation
O Divide both sides of the equation by two, then
determine the principal sguare root of both sides of
the eguaſh
O Determine the principal sguare root of both sides of
the equation
O Divide both sides of the equation by 2
