What is a 30 60 90 Triangle?
A 30 60 90 triangle is a special type of right triangle where the three angles measure exactly 30 degrees, 60 degrees, and 90 degrees. This fixed set of angles leads to consistent and predictable ratios between the lengths of the sides. 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.
