The length the hypotenuse of an isosceles right triangle, or a 45-45-90 triangle, is always radical two times as long as any leg of the triangle. With this, we can set up an equation where x represents the length of a leg.
x[tex] \sqrt{2} [/tex] = 8[tex] \sqrt{2} [/tex]
divide both sides by [tex] \sqrt{2} [/tex]
x = 8
The length of a leg of the triangle is 8
