Front

What is the length of the hypotenuse in a 45-45-90 triangle if one leg is 6?

Back

6√2

Front

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

Back

The length of the hypotenuse is twice the length of the short leg, and the length of the long leg is √3 times the length of the short leg.

Front

How do you find the length of a leg in a 45-45-90 triangle if the hypotenuse is 8?

Back

Divide the hypotenuse by √2.

Front

What is the measure of the angles in a 45-45-90 triangle?

Back

Both angles are 45°.

Front

If the short leg of a 30-60-90 triangle is 4, what is the length of the hypotenuse?

Back

8.

Front

What is the formula to find the length of the hypotenuse in a 45-45-90 triangle?

Back

Hypotenuse = leg × √2.
