In Figure, `X Pa n dX Q` are tangents from `X` to the circle with centre `OdotR` is a point on the circle. Prove that, `X A+A R=X B+B R`

In Figure,XP and XQ are tangents from X to the circle with centre O.R is a point on the circle.Prove that,XA+AR=XB+BR

In the figure PT is a tangent to the circle with centre 'O' then x =

In Figure, P A and P B are tangents from an external point P to a circle with centre O . L N touches the circle at M . Prove that P L+L M=P N+M N .

In the figure, PQL and PRM are tangents to the circle with centre O at the points Q and R respectively and S is a point on the circle such that |__SQL=50^(@) and |__SRM=60^(@) . Find |__QSR .

Circles with centres P and Q intersects at points A and B as shown in the figure. CBD is a line segment and EBM is tangent to the circle, with centre Q, at point B. If the circles are congruent, show that : CE = BD.

In Fig , XP and XQ are two tangents to the circle with centre O , drawn from an external point X . ARB is another tangent, touching the circle at R . Prove that XA + AR = XB + BR.
