Front

In a 45-45-90 triangle, if one side is known, how do you find the length of the other side?

Back

Use the same length for the other side.

Front

What is the definition of an adjacent side in a right triangle?

Back

The side that forms one of the angles with the hypotenuse.

Front

What is the definition of the hypotenuse in a right triangle?

Back

The longest side opposite the right angle.

Front

What is the definition of the opposite side in a right triangle?

Back

The side opposite the angle being referenced.

Front

How do you calculate the length of the hypotenuse in a 30°-60°-90° triangle?

Back

The hypotenuse is twice the length of the shorter leg.

Front

What is the relationship between the sides in a 45°-45°-90° triangle?

Back

The lengths of the legs are equal, and the hypotenuse is √2 times the length of a leg.
