Condition 3: The point of tangency is in the exterior of the circle.

• Condition 1 only

• Conditions 1 and 2

• Condition 2 only

• Conditions 1 and 3

What do you call a line segment from any point on the circle to its center?

• Radius

• Chord

• Diameter

• Secant

  circle.

• A radius of a circle is half of its diameter.

• A chord is any segment whose endpoints lie on the center of the circle.

• Semi-circle is half of a circle.

How is a chord different from a secant line in a circle?

• A chord intersects the circle at two points, while a secant line intersects at one point.

• A chord divides the circle into two equal parts, while a secant line divides it into unequal parts.

• A chord is contained entirely within the circle, while a secant line extends beyond the circle.

• A chord is always a straight line, while a secant line can be curved.
