Given an Iscosles Triangle with defined angle "delta". The other two angles are equal and bysected by the radius of a circle. Continuing the rays of the radius and two equal length sides of the triangle yields two equal angles "theta"a. I need to show that "delta" = 4*"theta"b - 2*"theta"a.(adsbygoogle = window.adsbygoogle || []).push({});

My work:

I assume that this is supposed to be two rays of light passing through a drop of water without any refraction.

I need to know whether "theta"b is the angle on the other side of "theta"a, or is it the other "half" of the bysected angles.

Its been too long since Ive done geometry, and I did not have a good professor
