Labelling Side Lengths - Right Angle Triangles

We learn how to label the adjacent and opposite sides as well as the hypotenuse in a right angle triangle. The adjacent and opposite sides are defined relative to an interior angle where as the hypotenuse is the side length opposite the right angle and is the longest side in a right angle triangle.
