A 30-60-90 triangle is a special type of right triangle that has a 30-degree angle and a 60-degree angle in addition to the right angle. This triangle has the angles labeled as shown in the diagram.

The definition of a right triangle is a triangle in which one of the interior angles measures 90 degrees. This 90-degree interior angle is also referred to as a right angle.

The legs of this right triangle are a and b, and the hypotenuse is c. Using this triangle, if a is 12 units long and c is 13 units long, use the Pythagorean Theorem to find the length of side b.
