Introduction to Trigonometric Ratios in Right Triangles

Angles and Angle Measurement → Reciprocal Trigonometric Functions

This learning path introduces the fundamental trigonometric ratios—sine, cosine, and tangent—as defined in right triangles. Starting from basic geometry of angles and triangles, it builds up to the definitions, the mnemonic SOH-CAH-TOA, and applications, including reciprocal functions.
