9 N Ine Given Figure Pa And Pb Are Two Tangents Drawnођ 43. in the given fig., pa and pb are two tangents drawn from an external point p to a circle with centre o. prove that op is the right bisector of line segme. Given, pa and pb are the two tangents drawn to a circle with centre o though an external point p. at point e on the circle the tangent is drawn which intersects pa and pb at c and d. given, pa = 10 cm. we have to find the perimeter of the triangle pcd. we know that the tangents drawn to a circle through an external point are equal. from the figure,. In the given figure, o is the centre of two concentric circles of radii 5 cm and 3 cm. from an external point p tangents pa and pb are drawn to these circles. if pa = 12 cm then pb is equal to (a) 5 2 cm (b) 3 5 cm (c) 4 10 cm (d) 5 10 cm. In the given figure, pa and pb are two tangents drawn from an external point p to a circle with centre c and radius 4 cm. if pa ⊥ pb then the length of each tangent. [cbse 2013] (a) 3 cm (b) 4 cm (c) 5 cm (d) 6 cm.
9 4 In The Given Figure Pa And Pb Are Two Tangents Draw In the given figure, o is the centre of two concentric circles of radii 5 cm and 3 cm. from an external point p tangents pa and pb are drawn to these circles. if pa = 12 cm then pb is equal to (a) 5 2 cm (b) 3 5 cm (c) 4 10 cm (d) 5 10 cm. In the given figure, pa and pb are two tangents drawn from an external point p to a circle with centre c and radius 4 cm. if pa ⊥ pb then the length of each tangent. [cbse 2013] (a) 3 cm (b) 4 cm (c) 5 cm (d) 6 cm. Given that pa and pb are tangents to circle. ∴ pa = pb. (∵ lengths of tangents to circle from a fixed outer point are equal.) ∴ triangle pab is an isosceles triangle. ∴ ∠pab = ∠pba. (∵ angles opposite to equal sides are always equal.) ∴ ∠pab = 65°. (∵ ∠pba = 65°(given)) since, pa is tangent to given circle and oa is. We know that tangents drawn from same point to the same circle are congruent. also, line joining the centre of this circle to the point of tangency is perpendicular i.e. angle formed by tangent and radius in $90^{\circ}$ oa and ob = 1 unit.
