What is the difference between a secant and tangent line

The video tutorial explains the differences between tangent and secant lines in the context of circles. A tangent line intersects a circle at exactly one point and is perpendicular to the radius at that point. In contrast, a secant line intersects the circle at two points. The tutorial provides definitions and properties of these lines to help students understand their roles in geometry.
