- Tim Brzezinski
4. Select the MOVE tool. Move point B around the circle. What do you notice?
5. Use the TANGENTS tool to construct a line passing through C that is tangent to the circle. How many tangents can be drawn from point C to the circle?
7. Use the DISTANCE OR LENGTH tool to measure the distance from C to E and the distance from C to F. What do you notice?
8. What two new properties can we conclude about tangents drawn to circles? Describe.
