Q4. Draw an angle of measure 153° and divide it into four equal parts.
The steps of constructions are:
(a) Draw a ray OA.
(b) At O, with the help of a protractor, construct ∠AOB = 153 degrees.
(c) Draw OC as the bisector of ∠AOB.
(d) Again, draw OD as bisector of ∠AOC.
(e) Again, draw OE as bisector of,∠BOC.
(f) Thus, OC, OD, and OE divide ∠AOB into four equal parts.
