Theorem The Lengths Of Tangents Drawn From An External Point To A 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:. Thus, it is proved that the lengths of the two tangents drawn from an external point to a circle are equal. the length of tangents drawn from any external point are equal. so statement is correct. .
Theorem The Lengths Of Tangents Drawn From An External Point To A If we draw two tangents from an external point to a circle, the lengths of these two tangents are equal. this can be proved by using the following concepts:1. 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. The lengths of two tangents from a common external point to a circle are equal. the two tangents will subtend equal angles at the center. the line that connects the exterior point to the center will divide the angle between the tangents into two equal angles. let’s consider two tangent lines pa and pb are drawn from an external point “p. It never intersects the circle at two points. the length of tangents from an external point to a circle are equal. tangent formula. suppose a point p lies outside the circle. from that point p, we can draw two tangents to the circle meeting at point a and b. now let a secant is drawn from p to intersect the circle at q and r. ps is the tangent.
