Tangent Radius Relationship in a Circle
- Tom Maes
Grab B and move it around the screen (make sure to change the length of the radius). What do you notice? Pay particular attention to the measure of angle ABC. Record any new observations or conjectures on your recording sheet and cross of any you previously made that you no longer believe to be true.
Make sure one of the conjectures on your recording sheet is related to the relationship between the radius and the tangent line.
