What is the definition of a chord?

• A line segment whose endpoints are on a circle.

• A line that passes through the center of the circle.

• A line segment that intersects at a point on the circle.

• A line that intersects a circle in two points.

What is the definition of a tangent?

• A line that intersects the circle on two points.

• A line that passes through the center of the circle.

• A line segment that passes through the center of the circle.

• A line that intersects the circle on only one point.

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 tangency?

• 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.
