The same side lengths can be used to evaluate the trigonometric functions of either acute angle in a right triangle. See . We can evaluate the trigonometric functions of special angles, knowing the side lengths of the triangles in which they occur. See . Any two complementary angles could be the two acute angles of a right triangle. If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa. See . We can use trigonometric functions of an angle to find unknown side lengths.
