CBSE Class 10 Maths (Basic) 2024 · Paper 430/4/1 · Question 22
XY and PQ are two tangents drawn at the end points of the diameter AB of a circle. Prove that XY || PQ.
Answer
Since is a diameter, the centre lies on it, so and (tangent perpendicular to radius). These are equal alternate angles made by the transversal , so . Hence proved.
