Class 9 - Math - Circles Page 176"

Answer 1

1.  Take three points P, Q,R on the circle.

2. Joint PQ and QR.

3.  Draw MT and NS which are the perpendicular bisectors of PQ and RQ and intersecting each other at a point O.

Hence, O is the centre of the circle.

Answer 2

Step of construction :-

1)Take 3 points A,B and C on the circumference of the circle.

2)Join AB and BC .

3)Draw PQ AND RE ,the perpendicular bisectors of AB. and BC,which interest each other at O.Then, O I the centre of the circle.
