This math unit introduces students to fundamental concepts in trigonometry, beginning with a focus on solving problems involving the ratios of line lengths in various geometric contexts such as parallel and right angle line displays. The progression continues as students practice calculating these ratios through visual and numerical formats, enhancing their understanding of how to apply trigonometric principles effectively. The unit takes a deeper dive into essential trigonometric functions by teaching students to identify and label the sides of triangles in relation to angles—introducing the sides as hypotenuse, opposite, and adjacent. This foundation supports learning the mnemonic "SOHCAHTOA" for remembering the relationships between sinusoidal functions (sine, cosine, and tangent) and the sides of right triangles. Subsequently, students engage in ratio manipulations and calculations of trigonometric identities, deepening their comprehension and ability to apply these skills in more complex scenarios. The focus towards the end culminates with practical applications, such as solving for unknown side lengths using trigonometric ratios expressed in different forms, thereby reinforcing a holistic understanding of trigonometry's real-world relevance.
