Answer:

BR bisects the angle ABC, and is called the bisector of angle ABC.

Step-by-step explanation:

Step 1:  Draw an arc with B as the centre to cut the arms, BA and BC, of the angle at P and Q respectively.

Step 2:  Using the same radius, draw an arc centred at P.

Step 3:  With centre Q and using the same radius, draw an arc to cut the arc in Step 2 at R.

Step 4:  Join, B, the vertex of the angle to the point R.
