Section 101 Tangents to Circles
Sep 24, 2014 · A line or segment that is tangent to two coplanar circles is called a common tangent A common internal tangent intersects the segment that joins the centers of the two circles A common external tangent does not intersect the segment that joins the centers of the two circles Example 3: Tell whether the common tangents are internal or external
INSCRIBED ANGLES, TANGENTS, AND SECANTS
investigate polygons inscribed in circles and polygons circumscribed about circles You will learn about a point of tangency and examine lines that are tangent to circles and how they relate to radii You will learn about secants and their connection with arcs, arc measure, and tangents Inscribed Angles Tangents Secants

Circles Part III - Sakshi Education
Definition: A common tangent L = 0 of the circles S = 0, S ′= 0 is said to be a transverse common tangent of the circles if the two circles S = 0, S ′ = 0 lie on the opposite (either) sides of L = 0 Centres of Similitude: Let S = 0, S ′ = 0 be two circles (i) The point of intersection of direct common tangents of S = 0, S ′
