Help with 10th grade geometry proof?
I am having extreme difficulty with this. I've tried using inscribed angle theorems, but I've given up. Can anyone solve this?Attachment 28158
I'm in tenth grade geometry. Thank you. Just click on the proof to enlarge it

Draw a line $\overrightarrow{BE}$
Make a point Z that is half way along $\overrightarrow{BE}$ (midpoint between B and E)

Draw a line $\overrightarrow{ZA}$

Through mirror symmetry, $\frac{\angle 1}{\overrightarrow{AB}}\frac{\cong}{\cong} \frac{\angle 2}{\overrightarrow{AE}}$

That should do it.

Hi,
I didn't really understand the previous answer. I think you have the right idea in trying to use the inscribed angle theorem. I hope you can prove your problem with the help of the following:
