What are the properties of a 45-45-90 triangle?

Back

In a 45-45-90 triangle, the legs are of equal length, and the length of the hypotenuse is equal to the length of a leg multiplied by √2.

What is the relationship between the sides of a 30-60-90 triangle?

Back

In a 30-60-90 triangle, the lengths of the sides are in the ratio 1:√3:2, where 1 is the length of the shorter leg, √3 is the length of the longer leg, and 2 is the length of the hypotenuse.

If the hypotenuse of a 45-45-90 triangle is 8√2, what is the length of each leg?

Back

Each leg would be 8, since the leg length is the hypotenuse divided by √2.
