Q2 of 33 Page 291

Draw an angle of measure 147° and construct its bisector.

Steps of Construction-

1. Draw a ray OA


2. With the help of protractor, construct ∠AOB = 147°



3. Taking centre O and any convenient radius, draw an arc which intersects the arms OA and OB at P and Q respectively.



4. Taking P as centre and radius more than half of PQ, draw an arc.


5. Taking Q as centre and with the same radius, draw another arc which intersects the previous at R.


6. Join OR and produce it.


Thus, OR is the required bisector of ∠AOB.
