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.

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.

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.

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

Two circles touch each other externally at point A and PQ is a direct common tangent which touches the circles at P and Q respectively. Then anglePAQ =

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.

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 the points P and Q. Two straight lines through P and Q intersect on circle at the points A and C and the other circle at B and D . Prove that AC||BD.

Two tangents drawn at the point A and B on a circle intersect each other at the point P. If angle APB=60^(@), then anglePAB=

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.

PQ is a diameter. The tangent drawn at the point R, intersects the two tangents drawn at the points P and Q at the points A and B respectively. Prove that angle AOB is a right angle.
