Specifically, the side opposite the 30-degree angle is the shortest and is half the length of the hypotenuse. The side opposite the 60-degree angle is √3 times the shortest side, making it √3 over 2 times the hypotenuse. Understanding these ratios is fundamental for solving a variety of geometric and trigonometric problems.
