Tangent Lines & Secant Lines of Circles, Walk Around Problem - Geometry

This geometry video tutorial provides a basic introduction into tangent lines and secant lines as it relates to circles. A secant line touches a circle at two points. A tangent line touches a circle at exactly one point. The radius of a circle and a tangent line are always perpendicular. This video also explains how to solve the walk around problem in geometry. Here is a list of topics: 1. Tangents and Secants of Circles 2. Tangent Lines & Radius of a Circle 3. Two Tangent Theorem 4. Tangent Circles 5. Internally Tangent vs Externally Tangent Circles 6.
