The picture below illustrates the general formula for the 30, 60, 90 Triangle.

30 60 90 and 45 45 90 Special Right Triangles

Although all right triangles have special features – trigonometric functions and the Pythagorean theorem. The most frequently studied right triangles, the special right triangles, are the 30, 60, 90 Triangles followed by the 45, 45, 90 triangles.

The picture below illustrates the general formula for the 30, 60, 90 Triangle.

The 30$$^{\circ}$$ and 60$$^{\circ}$$ angles give this one away.

x = 6

2x =12

z = $$ x \sqrt{3} = 6\sqrt{3} $$
