AB is tangent to the circle.

• TRUE

• FALSE

Can a secant be a tangent?

• yes they are both the same line

• yes they are both parts of a circle

• No secant intersects twice and tangent intersects once

• No they both have nothing to do with circles

What is the difference between a secant and a tangent

• A tangent is a line and a secant is a line segment

• A tangent passes through a circle once and a secant passes through the circle twice.

• A secant and a tangent are both chords but a tangent goes through the center of the circle

• A secant passes through the circle once and a tangent passes through the circle twice.
