I need help actually creating the proof. I've done the scratch needed for the problem, it's just forming the proof that I need help in.
Bar(a+bi/c+di)= (a-bi) / (c-di)
Bar ((a+bi/c+di)*(c-di/c-di)) = ((a-bi/c-di)*(c+di/c+di))
Bar((ac+bd/c^2 +d^2)+(i(bc-ad)/c^2+d^2)) =...
I just want to know if this proof is okay, and I would like advise on how to improve it.
Proof:
i. Proving that ∠BAC ⩭∠BDC:
Let gamma be the circumscribed circle of ABC.
Let D be the point on gamma such that DB is a diameter of gamma.
The sum of the angles within a triangle equal to 180°.
Adding...
Oh, my previous reply was my simplified answer after adding both fractions. I don't see how you simplified the denominator from the middle to the last part.
