A straight angle measures 180°, representing half of a 360° full turn. A right angle measures 90°, which is half of a straight angle. These are key geometric references for angle classification.

  1. A straight angle equals 180° because it represents a half-turn in a 360° rotation. A right angle measures 90°, which is precisely half of a straight angle and marks perpendicularity between two lines. These measurements serve as benchmarks in geometry, helping to define other angle types like acute, obtuse, and reflex. They provide the foundation for understanding rotational and angular relationships in mathematics.
