Part C
Look at the circle you created that has point C (the midpoint of AB ) as its center and passes through point A. What can you say about AB BDA BEA , and the measures of those two angles? Use what you know about the inscribed angle of a circle, and include your reasoning in your response.

Part E
What do the measures of angles BDA and BEA and the fact that AD and AE are radii of circle A tell us about BD and BE? Explain your answer.
