Define trigonometric ratios and solve problems involving right triangles. 6. Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles. 7. Explain and use the relationship between the sine and cosine of complementary angles. 8.

This looks similar to the Pythagorean Theorem with an additional complication at the end, and in fact that is true. Since the cosine of 90( is zero, for right triangles the last term will become zero and the formula will simplify to the familiar . The Law of Cosines is the general formula of which the Pythagorean Theorem is a special case.
