OP……...OQ, where O is the centre of the circle, P lies on the circle and Q is in the interior of the circle.

OP……...OR, where O is the centre of the circle, P lies on the circle and R lies in the exterior of the circle.

If O is the centre of the circle, then x is

Draw a circle with centre O and radius 6 c m . Mark points P , Q , R such that P lies on the circle, Q lies in the interior of the circle , and R lies in the exterior of the circle. Rewrite each of the following statements using the correct symbol (=, >): O Q 5 c m (ii) O P .5 c m (iii) O R .5 c m

For the four circles M, N, O and P, following four equations are given : Circle M : x^2 + y^2=1 Circle N : x^2 + y^2– 2x=0 Circle 0 : x^2 + y^2 - 2x - 2y +1=0 Circle P : x^2 + y^2 – 2y=0 If the centre of circle M is joined with centre of the circle N, further centre of circle N is joined with centre of the circle O, centre of circle O is joined with the centre of circle P and lastly, centre of circle P is joined with centre of circle M, then these lines form the sides of a :

(A) Choose the correct alternative : O is a centre of a circle, Tangents TP and TQ of the circles itersect at point T in the exterior of the circle. Points P and Q lie on the circle . If anglePOQ = 120^(@) then angle PTQ = ?

P, Q are the points on the circle. The part of the circle, PQ is called ________ of the circle.

O is the centre of the smaller circle,O' is the centre of bigger circle.CD is tangent to the smaller circle,Find the radius of the smaller circle.
