The steps for constructing an ∠ABC of measure 120∘ are given below in jumbled order:1. From the point R, mark a point P on the same arc with the same radius.2. Place the pointed end of the compass on B and draw a semi-circular arc with arbitrary radius and name its intersection with ray BC as Q.3. Draw a ray BC.4. From point Q, mark a point R on the arc with the same radius.5. Join B−P and extend it to obtain ray BAThe fifth step in the process is:
