Question

find the leg of.each isosceles right triangle when the hypothesis is 8 cm

Answer 1

The term is hypotenuse

Answer 2

(Continuing after the three hour delay)
The triangle is also a 45° 45° 90° triangle.
If we draw an altitude it will divide the hypotenuse in two.
The altitude and the half-hypotenuse are both 4 cm long.
SO, the length of the leg of the triangle is
sq root (4² + 4²)
=sq root (32)
=5.6568542495
