28 Σεπ 2008 · The document provides examples of calculating trigonometric ratios for various angles and triangles. It also examines ratios of complementary and special angles like 0, 30, 45, 60, 90 degrees. This document discusses triangle congruence theorems.
22 Νοε 2013 · The document provides examples of calculating trigonometric ratios for various angles and triangles. It also examines ratios of complementary and special angles like 0, 30, 45, 60, 90 degrees. Two angles are adjacent if they share a common side and vertex.
To find the trigonometric functions of special angles, first find the reference angle and then use the pattern to determine the ratio. For angles larger than 2π radians (360°), subtract 2π radians (360°) to find a coterminal angle, an angle that shares the same terminal side, that is less than 2π radians (360°).
