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 point of contact?

• 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.

A tangent to a circle is ________________________ to the radius drawn to the point of tangency.

• congruent

• perpendicular

• complimentary

• supplementary
