WebConcentric Circles : Two or more circles having same center is called the concentric circles. Circles touching each other: Two circles may touch each other either internally or externally. Let C 1, C 2 be the centers of the circle and r 1, r 2 be their radii and P the point of contact. Case (1) : The two circles touch externally : WebJan 9, 2024 · B – R – C ] [Theorem of touching circles] ∴ AB = AP + BP [A – P – B] ∴ AB = 3 + 3 = 6 cm Similarly, BC = 6 cm, AC = 6 cm So, if we construct triangle ∆ABC of side 6 cm each, then with A, B, C as the centres and radius 3 cm, the touching circles can be drawn. Question 12. Prove that any three points on a circle cannot be collinear
