Question

What is this the relationship between the legs and the hypotenuse of a 45 - 45 - 90 triangle?

Answer 1

Explanation:

The length of the hypotenuse and the legs of a 45 45 90 triangle are no different from any right triangle. It's simply:

a^2+b^2=c^2 where a and b are the legs and c is the hypotenuse.

Answer 2

The length of the hypotenuse is (the length of each leg) times (the square root of 2).
