Pretty Proof
We got out homework (as usual) in Geometry and Discrete Mathematics today and just about 5mins ago, Harry said he didn’t get question #6. It’s hard to explain such a graphical proof so I drew it instead. It’s so beautiful. Ironically enough, Harry stumbled upon the answer 5 seconds before I finished. :dizzy:
We basically have to prove that the chord AB bisects the angle DAC. All the black is given, the red has been drawn in. The not-so-formal proof on the right.
