This investigation will begin our understanding of circles and relationships among them. A basic understanding must be examined before proceeding.
In this example we will be looking at two circles and finding a circle that is tangent to both of them. Click Here to view the investigation.
Now that we have an understanding of the two circles lets look for different scenio's. First lets create a tool for finding the tangent circle to two circles.
Now lets examine what happens if we take and put circle B center on circle A. Click Here to view the investigation.
Now we can examine what happens if the circle B is outside of circle A. Click here for the investigation.
