This math unit begins with foundational trigonometry, starting with identifying different sides of a right triangle—opposite, adjacent, and hypotenuse. It progresses to understanding and labeling the side ratios in right triangles, using the SOHCAHTOA acronym to deepen the comprehension of trigonometric relationships such as sine, cosine, and tangent. As students become more comfortable with these definitions, they move on to applying and manipulating these ratios to solve for unknowns in trigonometric expressions and focusing on approximating trigonometric values from diagrams. The unit further advances into calculating and approximating side length ratios and explicit side lengths using trigonometric principles, scaling up to more complex applications where geometric figures and ratios are used extensively. Towards the end, the unit incorporates fact families within trigonometry to link geometric and algebraic representations, fostering a comprehensive grasp of the relationships between angles, sides, and trigonometric identities.
