Proof help please?

anonymous · Answer

Been trying to figure this out for a while but I don't understand

It must be a tough one.  It's so difficult you can't even enter it in this thread.

Show your Work.  Present the ENTIRE problem statement.

anonymous · Answer

Ya I was getting there

tkhunny · Answer

It helps if you put the information in the very first post.  There are notifications for the first post, but none for subsequent posts if no one responds.  Thus, many who could help skip right past your unhelpful first post.  Get it all in there up front.  1) Problem Statement, and 2) Your best efforts.

Well, in that case, it's not hard to find an example where it is false and we are done.

anonymous · Answer

actually those lines are perpendicular (my bad)

anonymous · Answer

EB⊥AO and  DC⊥FO

tkhunny · Answer

You didn't like the consequences?  Very good.

Things that come immediately to mind,
OA and OF are radii and are congruent.
Subtraction makes OB and OC congruent.
OE and OD (not drawn) are are RADII and are congruent.

Are we getting anywhere?  Some Right Triangle HL Theorem might come in handy.
