Trigonometry - Side Lengths from Variables and Identity (Level 1)

This math topic focuses on foundational trigonometry concepts involving side lengths and trigonometric identities. It includes problems where students must identify the relationships between sides of a triangle using sine, cosine, and tangent functions. The problems require selecting the correct trigonometric expression for given sides such as opposite, adjacent, or hypotenuse based on the provided trigonometric ratio. This forms a crucial part of understanding how to manipulate and use trigonometric identities and ratios to solve problems involving right-angled triangles.
