Trigonometric Ratios Explained: Sine, Cosine, Tangent in a Right Triangle #3327622 (License: Personal Use)

This educational diagram uses distinct colors to highlight the three sides of a right triangle-opposite (red), adjacent (blue), and hypotenuse (yellow)-alongside the angle θ. Labels clearly define sine, cosine, and tangent as ratios of these sides, supporting intuitive understanding of foundational trigonometry. The visual layout emphasizes relationships critical for solving triangles and modeling periodic phenomena.
