Question:
Using your protractor, draw an angle of 108°. With this given angle as given, draw an angle of 54°.
Solution:
Steps of construction:
1. Draw an angle ABC of 108°.
2. With B as the center and any radius draw an arc which intersects AB at P and BC at Q.
3. With P as center and radius more than half of PQ draw an arc.
4. With Q as the centre and same radius draw an arc which intersects the previous arc at R.
5. Join BR.
Therefore ∠RBC = 54°
