In geometry, tangent circles (also known as kissing circles) are circles in a common plane that intersect in a single point. There are two types of tangency: internal and external. Tangent circles - Wikipedia To construct a circle touching a given circle. Circle O, radius = 30 mm; circle C, radius = 20 mm. Draw circle O. Draw any line OT passing through centre O. Set compasses to the sum of the the two radii - 30 + 20 = 50 mm. With centre O strike arc of 50 mm radius along lin OT to give C. Then C is the centre of the tangential circle. por DEBORAH DEVEAUX 1 To construct a circle touching a given circle. Circle O, radius = 30 mm; circle C, radius = 20 mm. Draw circle O. Draw any line OT passing through centre O. Set compasses to the sum of the the two radii - 30 + 20 = 50 mm. With centre O strike arc of 50 mm radius along line OT to give C. Then C is the centre of the tangential circle. 2 To construct a circle touching a given circle. Circle O, radius = 30 mm; circle C, radius = 20 mm. Draw circle O.
