Question
In your note-book copy the following angle using ruler and a pair compass only.
Solution
Steps of Construction:
1. At point Q, draw line QR = OB.
2. With O as a centre, draw an arc of any suitable radius, to cut the arms of the angle at C and D.
3. With Q as a centre, draw the arc of the same size as drawn for C and D. Let this arc cuts line QR at point T.
4. In your compasses, take the distance equal to distance between C and D; and then with T as a centre, draw an arc which cuts the earlier arc at S.
5. Join QS and produce up to a suitable point P. ∠PQR so obtained, is the angle equal to the given ∠AOB.
