Which is angle 2 and 3? No matter, you can still solve it.

I don't want to flat out give you the answer, but first you need to mention that if you have two lines of equal length, and if you subtract 2 similar lines (respectively) of equal length, you will be left with 2 lines of equal length, thus proving what you need to prove. Should only take you 2-3 additional steps, depending on the method of which you choose.
