## Conjecture 1

Look at the image below. In our picture we have three circles (c1, c2, and c3). I have constructed the picture, but I have hidden all of the identifying objects that may have helped to determine any relationships between the circles. Make any conjectures about the image. To confirm or adjust your conjecture you may click on the link for a table of terms to see a picture and a definition of the terms.

## Conjecture 2

In the last image, we were able to observe some relationships between the circles. Although it is nice to observe those important facts about the image above, we need to see if the relationships change when we change one of the variables. If this were to happen then our image would not be able to prove anything about circles, it would merely be a nice picture. The question is, then, what do you think will happen when point B travels around the path of c1?

Click on the image to see what happens to the relationship between the circles when point B travels around circle c1.
