Right Triangle Trigonometry Diagram - Hypotenuse, Opposite, Adjacent Sides Explained #3699753 (License: Personal Use)

This diagram illustrates a right triangle ABC with the right angle at C, where side AB (length h) is the hypotenuse, BC (length a) is opposite angle α at A, and AC (length b) is adjacent to α. The yellow sectors highlight angle α and the right angle for clarity. Labels use standard color coding: red for hypotenuse, green for opposite, blue for adjacent.
