Draw an angle of measure 153° and divide it into four equal parts.
Steps of Construction-
1. Draw a ray OA
2. At O, with the help of a protractor, construct ∠AOB = 153°
3. Draw OC as the bisector of ∠AOB.
4. Again, draw OD as bisector of ∠AOC.
5. Again, draw OE as bisector of ∠BOC.
Thus, OC, OD and OE divide ∠AOB in four equal.
