Two tangents PA and PB are drawn to circle with centre O from an external point P. Prove that angleAPB= 2angleOAB

Two tangents PA and PB are drawn to a circle with centre O from an external point P. Prove that angle APB = 2 angle OAB

In the figure , tangent PA and PB are drawn to a circle with centre O from an external point P. If CD is a tangent to the circle at E and AP = 15cm, find the perimeter of Delta PCD .

From the external point P tangents PA and PB are drawn to a circle with centre O. If angle PAB = 50^(@) , then find angle AOB .

In the figure, tangents PA and PB are drawn to a circle with centre O from an external point P. If CD is a tangent to the circle at E and AP=25cm, find the perimeter of /_\PCD .

PA and PB are tangents to the circle with centre O from an external point P , touching the circle at A and B respectively. Show that the quadrilateral AOBP is cyclic.

PA and PB are the two tangents drawn on a circle from and external point P. The centre of the circle is O and the tangents touches the circles at points A and B. Then quadrilateral OAPB is-
