Ask students to use a calculator to find the sine, cosine, and tangent of pairs of complementary acute angles, angle A and angle B. In a class discussion, ask students what observations they can make about the trigonometric ratios. Lead students to discover that the sines and cosines of complementary angles are equal to one another.
