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

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle.

Front

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

Back

The opposite side is the side opposite to the angle of interest in a right triangle.

Front

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

Back

The adjacent side is the side next to the angle of interest in a right triangle, excluding the hypotenuse.
