From the figure, answer the following : (c) Line segment PQ is ______ of circle.

From the figure, answer the following : (e) Line segment MN is ______ of circle.

From the figure, answer the following : (d) Line setment OP is ______ of circle.

From the figure, answer the following : (b) Line segment OQ is the ______ of the circle.

From the figure, answer the following : (a) O is the ______ of the circle,

In the given figure, O is the centre of the circle and PQ is one of its diamtere, then the value of x is

The centre of two circle are P and Q they intersect at the points A and B. The straight line parallel to the line segment PQ through the point A intersects the two circles at the point C and D Prove that CD = 2PQ

Let P be a variable point on a circle C and Q be a fixed point outside C. If R is the midpoint of the line segment PQ, then locus of R is

The circle x^2+y^2=1 cuts the x-axis at Pa n dQdot Another circle with center at Q and variable radius intersects the first circle at R above the x-axis and the line segment PQ at S. Find the maximum area of triangle QSR.

Two circles intersect each other at the points G and H . A straight line is drawn through the point G which intersect two circles at the points P and Q and the straight line through the point H parallel to PQ intersects the two circles at the points R and S . Prove that PQ=RS .
