Answer:

Steps of construction:

Step 1: Draw an obtuse angle. We choose ∠ABC=120

0

.

Step 2: Draw an arc which intersects AB at P and BC at Q, from center B and choose any radius.

Step 3: Draw an arc from point P by setting radius more than half of PQ.

Step 4: Repeat step 3 using Q as center and cut the previous arc at R.

Step 5: Join BR.

The diagram is shown in the above image.

Therefore, ∠ABR=∠RBC=60

0
