Question

 Draw an angle and label it as ∠BAC. Construct another angle, equal to ∠BAC.

Answer 1

Steps of construction:
1. Draw an angle ABO and a Line segment QR
2. With center A and any radius, draw an arc which intersects `∠`BAC at E and O
3. With center Q and same radius draw arc which intersect QR at S.
4. With center S and radius equal to DE, draw an arc which intersect previous arc at T
5. Draw a line segment joining Q and T

∴ `∠`PQR =  `∠`BAC
