Circles: Lines and Segments

A radius:

• A segment whose endpoints are on the circle and passes through the center

• A segment whose endpoints are on the circle

• A segment whose endpoints are the center and any other point on the circle

A diameter:

• A segment whose endpoints are on the circle and passes through the center

• A segment whose endpoints are on the circle

• A segment whose endpoints are the center and any other point on the circle

A chord:

• A segment whose endpoints are on the circle

• A line that intersects the circle at exactly one point

• A line that intersects the circle at two points

A tangent:

• A segment whose endpoints are on the circle

• A line that intersects the circle at exactly one point

• A line that intersects the circle at two points

• A segment whose endpoints are the center and any point on the circle

A secant:

• A segment whose endpoints are the center and any point on the circle

• A segment whose endpoints are on the circle

• A line that intersects the circle at two points

• A segment whose endpoints are on the circle and pass through the center
