A tangent line intersects a circle at how many points?

A tangent line and the radius of a circle form what kind of angle?

What is the Pythagorean Theorem?

## In the picture below, AB is the radius and BC is a tangent line to the circle.

What is the measure of angle ABC?

What is the length of segment AC? (show your work)

## In the picture below, AB is the radius and BC is a tangent line to the circle.

What is the measure of angle ABC?

What is the radius of the circle pictured above? (show your work)

## In the picture below, AB=3, BC=4, and AC=5

Use the Pythagorean Theorem to determine if BC is tangent to Circle A.
