This math unit begins with foundational trigonometry skills, focusing on calculating trigonometric ratios given triangle side lengths and progressing to determine angles using these ratios. Students practice solving for unknown side lengths and angles from basic numerical data and then advance to solving from diagrams. As the unit progresses, the complexity increases as students engage with specific trigonometric rules—the Rule of Sines and Rule of Cosines—starting with setups and moving into full calculations. These principles are applied to solve for side lengths and angles in various triangles, including non-right triangles. Towards the end of the unit, students use trigonometric functions to solve for practical aspects like the areas of triangles, utilizing these more advanced concepts to setup and compute areas using given sides and angles. This progression builds a comprehensive skill set in solving common and complex trigonometric problems in geometry.
