Continuing with the previous question, what angle do we have at the end of four arcs?
With B as the centre and any radius more than half of AB, draw another arc as shown. This is the third arc. With A as the centre and the same radius as above, cut the previously drawn arc in Y. This would be the fourth arc. Join PY.

The steps to construct 75∘ angle is given below. Arrange these steps in the correct sequence.
1. At the point O, draw an angle AOE = 60∘.
2. Bisect the ∠DOE.
3. Draw an angle AOD = 90∘ at a point O on the line segment OA.

Steps of construction are:
Step 1: Draw a ray AB
Step 2 will be:
- Taking D as center and any radius, draw an arc intersecting the previous arc at E.
- Using protractor, draw an angle 60∘.
- Taking D as center and same radius, draw an arc intersecting the previous arc at E.
- Taking A as centre and any convenient radius, draw an arc intersecting ray AB at a point D.
