Trigonometric Ratios and the Pythagorean Theorem

From the Illustrative Mathematics website, "The purpose of this task is to use the Pythagorean Theorem to establish the fundamental trigonometric identity sin²Θ¸+cos²Θ¸=1 for an acute angle Θ¸. The reasoning behind this identity is then applied to calculate cosΘ¸ for a given obtuse angle. In order to successfully complete part (c) students must be familiar with the definitions of trigonometric functions for arbitrary angles using the unit circle."
