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.

What is a tangent line in relation to a circle?

• A line that intersects a circle at two points

• A line that does not touch the circle

• A line that is parallel to a circle

• A line that intersects a circle at one point

What is the relationship between a tangent line and the radius at the point of tangency?

• They are parallel

• They are perpendicular

• They intersect at two points

• They do not intersect

What do we call a line that intersects a circle at two different points?

• Parallel line

• Tangent line

• Chord

• Secant line

Which of the following is true about a secant line?

• It is parallel to the tangent line

• It intersects the circle at one point

• It intersects the circle at two points

• It is perpendicular to the radius at the point of tangency

How does a tangent line differ from a secant line?

• A tangent line intersects at one point, while a secant line intersects at two points

• A tangent line intersects at two points, while a secant line intersects at one point

• A tangent line is inside the circle, while a secant line is outside

• A tangent line is parallel to the circle, while a secant line is not
