A tangent is a line that touches a circle at just one point and forms a right angle with the circle's radius.

• True
• False

In the diagram, a tangent and a line drawn to the point of tangency form a right triangle. Solve for "?" (the length of the hypotenuse)

What can you conclude from the picture?

• m is parallel to circle C
• m is skew to circle C
• m bisects circle C
• m is tangent to circle C

What can you conclude?

• AB and AC are not congruent.
• AB= half of AC
• AC = half of AB
• AB=AC
