Q.1 Draw different pairs of circles. How many points does each pair have in common? What is the maximum number of common points?

Ans

Different pairs of circles are given below:

There are zero common points in figure (a) and (d).

There is one common point in figure (b). There are two common points in figure (c).

Thus, maximum number of common points is 2.

Q.2 Suppose you are given a circle. Give a construction to find its centre.

Ans

Given: Let there are three point A, B and C on the circumference.

To find: Centre of circle.

Steps of construction:

(i) Join A and B, B and C.
(ii) Draw perpendicular bisector of AB and BC.

The intersection point O, of perpendicular bisector is called centre of circle.

Q.3 If two circles intersect at two points, prove that their centres lie on the perpendicular bisector of the common chord.

Ans

Given: Two circles with centre O and O intersect at A and B.                AB is common chord of both circles.To prove: Centres O and O lie on the perpendicular bisector of                       AB i.e., OO is perpendicular bisector of AB.Proof: In ΔOAO and ΔOBO             OA=OB               [radii of same circle.]           OO=OO            [Common]          OA=OB              [radii of same circle.]         ΔOAOΔOBO       [By S.S.S.]         AOO=BOO      [By C.P.C.T.]         AOO=BOO      [By C.P.C.T.]       In ΔOAP and ΔOBP            OA=OB               [radii of same circle.]    AOP=BOP       [Proved above]             OP=OP               [Common]      ΔOAPΔOBP         [By S.A.S.] So,AP=BP[ By C.P.C.T. ] OPA=OPB[ By C.P.C.T. ] ButOPA+OPB=180° OPA=OPB=90° OP is perpendicular bisector of AB. OO is perpendicular bisector of AB. O and O’ lies on perpendicular bisector of AB. Hence proved.
