Class 6 Mathematics Chapter 2 Lines and Angles question answer
A straight angle, created by a half-turn, measures 180 degrees. A right angle, being half of this, is formed by a quarter-turn rotation and measures 90 degrees. This relationship divides the full 360-degree rotation into four equal parts. Right angles are significant in geometry, marking perpendicularity and symmetry, and are easily recognizable as they resemble the shape of an “L.”
