Geometric Proofs...4

diameters AB and CD crossing each other at the center E, and dividing 360 degrees into 4 angles: angle AEC, angle AED, angle DEB, and angle BEC

statement.........................................................reason
1. angle AEC=angle DEB .................... by def. of vertical angles
2. arc AC=arcDB.................................... the angles at the circumference subtended by the same arc are equal

Is this entire proof?

 

[MathLover1]

yes

 

[nycmathguy]

yes

1. Who taught you how to do this stuff?
2. There are 3 answered geometric proofs in this forum.

There are math teachers out there that, believe it or not, struggle with geometric proofs. Did you know that? In 2006, I met a retired professor whose username was Soroban. A very intelligent man.

Soroban taught college mathematics for 25 in the Boston Massachusetts area. I requested his help with geometric Proofs then but he was not able to help me. The same thing with another math wiz who called himself MarkFL. Two very intelligent men who could not help me with geometric proofs. How about that?

I know that there are math teachers out there that struggle with geometric proofs
not every math teacher is good in geometry, so those who are not tend to avoid proofs
I did like proofs of all kind, and that is a reason I have trouble believing in something without valid proof

I don't want to bring God into this chat.

1. The Bible clearly teaches that without faith it is impossible to believe in God. The apostle Paul defined faith this way:

FAITH IS THE SUBSTANCE OF THINGS HOPED FOR, THE EVIDENCE OF THINGS NOT SEEN.

2. Mira, if you call Jesus in prayer; in you are patient and don't fuss or get upset, in all humility ask for Him, Jesus will come to you VISIBLY or some other way proving that His presence is there. TRY IT....

3. You know proofs well for someone who did not like it all.

4. I like geometric proofs. I just don't get it.

enough of comments about god, please delete that above if you want me to be here
this is my last warning and I am serious
