Recognizing special right triangles in geometry can help you to answer some questions quicker. A special right triangle is a right triangle whose sides are in a particular ratio. You can also use the Pythagorean theorem, but if you can see that it is a special triangle it can save you some calculations.
In this lesson we will study the special right triangle called the 30°-60°-90° triangle.
30º-60º-90º Triangles
Another type of special right triangles is the 30°- 60°- 90° triangle. This is right triangle whose angles are 30°, 60°and 90°. The lengths of the sides of a 30°- 60°- 90° triangle are in the ratio of 
.
The hypotenuse is always twice the length of the shorter leg (the side facing the 30° angle). The longer leg (the side facing
