प्रश्न
Using your protractor, draw an angle of measure 108°. With this angle as given, draw an
angle of 54°.
उत्तर
Steps of construction:
1. Draw an angle ABC of 108°
2. With center B and any radius, draw an arc which intersects AB at P and BC at Q
3. With center P and Q and radius more than `1/2`PQ draw two arcs, which intersect each other at R.
4. Join BR
∴`∠`RBC = 54°
