The applet below illustrates properties that involve the

**angles**and**arcs****of circles**that must always hold true.## What do you think the moving applet below is demonstrating?

Write a conjecture (in sentence form) that summarizes your observations.

## Next, move point C and point D in the applet below.

As you move these points, observe what happens to the size of the inscribed angles.
What relationship is ALWAYS true regarding the measures of the

**green**,**red**, and**blue**angles?
