Re: Circumscribed triangle!!!

Okay, then go ahead with it.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Circumscribed triangle!!!

But I don't know how to prove it!

That is why I left it out.

hi hammana

That doesn't prove what we need.

Re: Circumscribed triangle!!!

Hi anonimnystify

I will try to make myself clear. I refer to your figure in post #24 (I do'nt know yet how to post a figure). If C1 is the center of circle ABD, Its projection H1 on CD is the middle of AD. The projection H2 of C2, center of the circle ABC, is the middle of AC. H1 H2 = C1 C2 = CD/2. the length of CD is twice the distance of the centers C1 C2. If we draw any other line passing through A,  making an angle x with C1 C2, and intersecting the circles at P and Q, the same reasoning shows that the distance PQ is 2*C1 C2*cos(x) . The factor cos(x) makes the difference.
