Ex 10 2 10 Prove That Angle Between Two Tangentsо 10. prove that the angle between the two tangents drawn from an external point to a circle is supplementary to the angle subtended by the line segment joining the points of contact at the center. answer: first, draw a circle with centre o. choose an external point p and draw two tangents pa and pb at point a and point b, respectively. The two radii and the line segment joining the points of tangency form a triangle within the circle. the angle between the two tangents, drawn from the external point, acts as an external angle to this triangle. according to the external angle theorem in geometry, an external angle of a triangle is equal to the sum of the two opposite internal. Ncert solutions class 10 maths chapter 10 exercise 10.2 question 10. summary: it has been proved that the angle between the two tangents drawn from an external point to a circle, that is, ∠apb is supplementary to the angle subtended by the line segment joining the point of contact at the centre, that is, ∠aob. thus, ∠apb ∠boa = 180°. So, the result that the tangents drawn from an external point are equal, will be applied here. question 9. in fig. 10.13, xy and x′y′ are two parallel tangents to a circle with centre o and another tangent ab with point of contact c intersecting xy at a and x′y′ at b. prove that ∠ aob = 90°. solution:.
