CBSE Class 10 Maths (Standard) 2020 · Paper 30/1/1 · Question 37
Draw a line segment of length cm. Taking as centre, draw a circle of radius cm and taking as centre, draw another circle of radius cm. Construct tangents to each circle from the centre of the other circle.
Answer
Two tangents from to the cm circle (at ) and two tangents from to the cm circle (at ) are obtained using a single helper circle drawn on as diameter; the contact points see at , so each joining line is tangent.
