प्रश्न
Construct the 15° angle, using ruler and a pair of compass only.
उत्तर
Steps of construction:
To construct an angle of 15°.
- Draw an angle of 60° as drawn above.
- Bisect this angle of get two angles each of 30°. Thus, ∠EOB = 30°
- Bisect this angle ∠EOB to get two angles each of 15°. ∠EOB = 15°.
