Question

What is the length of the leg in a 45-45-90 triangle with a hypotenuse of 1?

Answer 1

√2 / 2

Explanation:

In a 45-45-90 triangle, the length of a leg is equal to the hypotenuse / √2

Therefore, the length of a leg is 1 / √2

Rationalize by multiplying the numerator and denominator by √2, and this becomes √2 / 2
