Figure 1: 30 60 90 Triangle
The right triangle defined by the three angles: , and is a special triangle that has meaningful properties in mathematics.
The general form of the triangle, shown below, can be given in terms of , where measures the length of the opposite side of the triangle.
The 30-60-90 triangle measured in radians has the following measurements:
Radians are a unit that measure angle using the radius of a circle. One radian is equal to the amount of rotation required to travel the length of one radius along the circumference of the circle.
