What is the definition of a secant line

The video tutorial discusses the concepts of tangent and secant lines in geometry. It explains that 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 a circle at two points. The teacher emphasizes understanding the differences between these lines, as students will encounter directions related to these concepts.

Describe a scenario where a line intersects a circle at two points.

How can you draw a line that is perpendicular to a secant line?
