IM2.7 T6 Cyclic Quadrilaterals
- Lind, Jon, Tim Brzezinski
Any quadrilateral that is inscribed inside a circle is said to be a cyclic quadrilateral. In the applet below, a cyclic quadrilateral (with moveable vertices) is shown. Slide the slider slowly and carefully observe what happens. Then, reset the applet. Change the locations of the BIG POINTS and repeat this process. Repeat the previous steps a few more times. Then, answer the questions that follow.
1) Suppose, in the applet above, the red angle measures 76 degrees. What would the measure of the blue angle be?
