Draw an angle of 110° with the help of a protractor and bisect it. Measure each angle.

Solution:

Construct ∠BXA = 110° using a protractor

Steps of Construction

Draw an angle of 110° with the help of a protractor and bisect it. Measure each angle

1. Consider X as centre and taking any radius construct an arc which intersects the rays XA and XB i.e. E and D

2. Considering D and E as centres and radius more than half of DE, construct arcs which intersect each other at F

3. Construct the ray XF

4. XF is the required bisector of angle BXA

5. By measuring each angle

∠BXC = ∠AXC = 1/2 ∠BXA = 110/2

∠BXC = ∠AXC = 55°

Therefore, each angle is 55°.

✦ Try This: Draw an angle of 90° with the help of a protractor and bisect it. Measure each angle.
