Draw an angle of 110° with the help

Draw ∠BXA = 110° with the help of a protractor. Now, we use the following steps for required construction

1. Taking X as centre and any radius daw an arc to Intersect the rays XA and XB, say at E and D, respectively.
2. Taking D and E as centres and with the radius more than ½ DE, draw arcs to intersect
   each other, say at F.
3. Draw the ray XF.
   Thus, ray XF is the required bisector of the angle B X A. On measuring each angle, we get
   ∠BXC = ∠AXC = 55°.
   [∴ ∠BXC = ∠AXC = ½ ∠BXA = ½ x 110° = 55° ]
