Right Triangle Diagram: Sides a, b, h and Angle α Labeled #295634 (License: Personal Use)

This diagram illustrates a standard right triangle ABC, where ∠C is the right angle, side b lies along the horizontal axis (adjacent to ∠A), side a is vertical (opposite ∠A), and h is the hypotenuse connecting A and B. Angle α at vertex A is explicitly marked, supporting trigonometric ratio definitions (sin α = a/h, cos α = b/h, tan α = a/b). The clean, minimal labeling makes it ideal for instructional use.

Used in educational web pages, math tutorials, trigonometry guides, and STEM curriculum materials to explain Pythagorean theorem, sine/cosine/tangent ratios, and triangle properties. Matches user intent for visual aid in solving geometry problems or learning foundational trig concepts.
