basics of chord, secants and tangents

What is the difference between a tangent line and a secant line?

• A secant intersects the circle twice; a tangent touches the circle once

• A tangent intersects the circle twice; a secant touches the circle once

• A secant goes through the center of the circle; a tangent does not

• A secant is outside the circle; a tangent is inside the circle

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.
