    Re: Help with 10th grade geometry proof?

    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:
