Clock hands create angles like 30° (1 o’clock), 90° (3 o’clock), and 210° (7 o’clock). Acute angles are under 90°, obtuse angles range from 90° to 180°, and reflex angles exceed 180°.

Class 6 Mathematics Chapter 2 Lines and Angles question answer
The clock hands form various angles throughout the day. At 1 o’clock, they form 30°; at 3 o’clock, a 90° right angle; and at 7 o’clock, a 210° reflex angle. Smaller angles like 30° are acute, while larger ones like 120° or 150° are obtuse. Reflex angles appear when the hands exceed 180°, such as 210° or 330°. Understanding these angles aids in learning geometry and visualizing rotational measures in a circle.
