The diagram will be as shown above.

Steps of construction:

Step I- With the help of protractor, draw an angle of 80

∘

. Name the rays OA and OB.

Step II - Cut OA and OB at Q and P, taking O as the center and any convenient radius, with the help of the compass.

Step III - With vertex P, by using compass take more than half of arc PQ and draw arc.

Step IV - With vertex Q, by using compass with same length, cut the previous arc at R.

Step V- With help of ruler, join the point O and R.

∴  ∠AOR=∠ROB

Step VI - Similarly, bisect the arcs QS and SP

∴       ∠AOV=∠VOR and  ∠ROU=∠UOB

Thus, ∠AOV,  ∠VOR,  ∠ROU and  ∠UOB divide ∠BOA in four equal parts

You can verify this by using a protractor.

∴ ∠AOV=∠VOR=∠ROU=∠UOB=20 degree
