Web2. CIRCLES (10) Periods Tangent to a circle at, point of contact 1. (Prove) The tangent at any point of a circle is perpendicular to the radius through the point of contact. 2. (Prove) The lengths of tangents drawn from an external point to a circle are equal. WebSolution Consider 2 circles, one with centre 'O', and another with 'O 1 '. [1 Mark] Radius of the bigger circle = r1 = 10 cm Radius of the smaller circle = r2 = 4 cm The 2 circles touch each other at X internally. OX = r1 = 10 cm O1X =r2 = 4 cm [1 Mark] Distance between their centres = OO1 =XO−XO1 = r1−r2 = 10 - 4 = 6 cm [1 Mark]
