## Follow the directions below to interact with the applet and answer the questions.

1. Use the tangent tool to create a tangent line through point C and then a different tangent line through point B. To use the tool, first click on point C and then click on the circle. Do the same thing with point B.

2. Use the point intersection tool to create a point where the two tangents meet.

3. Use the distance tool to measure the distance from point C to the intersection point of the tangent lines and then measure the distance from point B to the intersection point of the tangent lines. What do you notice about these distances?
