Laxmi has drawn two circles which intersect each other at O externally. If PQ and RS be two parallel diameters of trhe circles, then prove that the points P, O and S are collinear.

Parama drew to circles intersect each other at the points P and Q . If the diameter of the two ircels are PA and PB resepctively , then prove that A,Q,B are collinear.

Answer any one question : Two circle intersect each other at the points P and Q. If the diameters of the two circle are PA and PB respectively, then prove that A, Q, B are collinear.

Two circle intersect each other at A and B and a straight line parallel to AB intersects the circles at C,D,E,F. Prove that CD = EF.

Ankita drew two circles which intersect each other at the points P and Q. Through the point P two straight lines are draw so that they intersect one of the circle at the points. A and B and the ohte circle at the points C and D respectively. Prove that angle AQC= angle BQD .

Two circles intersect each other at P externally. The straight QR touches the circle at two points Q and R. Prove that /_QPR = 1 right angle.

If two circles intersect each other, then the number of their common tangents will be

Two circles touch each other at the point R. PQ is a common tangent to both the circle which touches the circle at the points P and Q. Then anglePRQ=

In two circles , one circle passes through the centre O of the other circle and they intersect each other at the points A and B . A straight line passing through A intersect the circle passing through O at the point P and the circle with centre at O at the point R . BY joining P , B and R , B prove that PR= PB.

Each of the two equal circles passes through the centre of the other and the two circles intersect each other at the points. A and B.If a straight ine through the point A intersects the two circles at points C and D prove that Delta BCD is an equilateral triangle.
