Trigonometric Ratios Explained: Sine, Cosine, and Tangent Diagram #295630 (License: Personal Use)

This educational diagram uses red, green, and yellow triangles to illustrate the fundamental trigonometric ratios in a right-angled triangle. The red triangle highlights the sine ratio (opposite/hypotenuse), the green shows cosine (adjacent/hypotenuse), and the yellow emphasizes tangent (opposite/adjacent), with angle θ at the base. Labels such as “adjacent,” “opposite,” “hypotenuse,” and Greek letters α and β further clarify geometric relationships.

Used in math education websites, online textbooks, and classroom slides to teach introductory trigonometry; matches user intent for visual learning of SOH-CAH-TOA concepts.
