In the figure, PO_|_QO. The tangents to the circle with centre O at P and Q intersect at a point T. Prove that PQ and OT are right bisectors of each other.

In the given figure,PO perp OQ.The tangent to the circle with centre 0 at P and Q intersect at a point T.Prove that PQ and OT are right bisectors of each other.

Two parallel tangents of a circle meet a third tangent at points P and Q. Prove that PQ subtends a right angle at the centre.

Tangents to a circle at points P and Q on the circle intersect at a point R. If PQ= 6 and PR= 5 then the radius of the circle is

Two radii OA and OB of a circle with centre O are perpendicular to each other. If two tangents are drawn at the point A and B intersect each other at the point T, prove that AB= OT and they bisect each other at a ridght angle.

In the diagram above, ABCD is a square . The circles , whose centers lie on bar(BD) , are congruent to each other . The sides of the square are tangent to the outer circles at P,Q,R and S , and the circles are tangent to each other at K and L . If the radius of each circle is 1 inch. What is the area , to the nearest square inch, of the square ?

Prove that the tangent and the radius through the point of contact of a circle are perpendicular to each other.
