Prove That The Lengths Of Tangents Drawn From An External Point To A

The Length Of Tangents Drawn From An External Point Point Outside The Q) prove that the lengths of tangents drawn from an external point to a circle are equal. using above result, find the length bc of Δ abc. given that, a circle is inscribed in Δ abc touching the sides ab, bc and. ca at r, p and q respectively and ab= 10 cm, aq= 7cm ,cq= 5cm. ans: (i) tangent equal from an external point:. Transcript. theorem 10.2 (method 1) the lengths of tangents drawn from an external point to a circle are equal. given: let circle be with centre o and p be a point outside circle pq and pr are two tangents to circle intersecting at point q and r respectively to prove: lengths of tangents are equal i.e. pq = pr construction: join oq , or and op proof: as pq is a tangent oq ⊥ pq so, ∠ oqp.

Solution. let ap and bp be the two tangents to the circle with centre o. to prove : ap = bp. proof : in Δ aop and Δ bop. oa = ob (radii of the same circle) ∠oap =∠obp = 90∘ (since tangent at any point of a circle is perpendicular to the radius through the point of contact) op = op (common) ∴ Δaop ≅Δbop (by r.h.s. congruence criterion). Given, tp and tq are two tangent drawn from an external point t to the circle c (o, r). to prove: tp = tq construction: join ot. proof: we know that a tangent to the circle is perpendicular to the radius through the point of contact. To prove: the lengths of tangents drawn from an external point to a circle are equal . let pq and pr be the two tangents drawn to the circle of centre o as shown in the figure. construction. draw a line segment, from centre o to external point p { i.e. p is the intersecting point of both the tangents} now ∆por and ∆poq.

How many tangents do you think can be drawn from an external point to a circle? the answer is two, and the following theorem proves this fact. theorem: exactly two tangents can be drawn from an exterior point to a given circle. consider the following figure, in which a tangent has been drawn from an exterior point p to a circle s (with center o. A tangent touches a circle at only one point. a tangent is a straight line that never enters the interior of the circle. the tangent makes a right angle at the point of tangency with the radius of a circle. tangents drawn from an external point to a circle have the same length. a circle can have infinitely many tangents.
