प्रश्न
Construct the 30° angle, using ruler and a pair of compass only.
उत्तर
Steps of construction:
To construct an angle of 30°.
- Draw a line OB of any suitable length.
- At O, draw an arc of any size to cut OB at D.
- With D as a centre, draw the same size arc, to cut the previous arc at C.
- Join OC and extend up to a suitable point A. Then, ∠AOB = 60°.
- Bisect this angle of get two angles each of 30°. Thus, ∠EOB = 30°.
