What is the definition of a secant?

• A line segment whose endpoints are on the circle.

• A line that intersects a circle in one point.

• A line that intersects a circle in two points.

• A line segment which intersects the circle at the point of secancy.

What is the point of contact?

• The point where the tangent intersects a circle.

• The point where the tangent interssects the center of the circle.

• The point where the tangent intersects with another tangent.

• The point where the tangent intersects with a secant.

What can you conclude from the picture?

• m is parallel to circle C

• m is skew to circle C

• m bisects circle C

• m is tangent to circle C
