Hi, I have to do a vertical angle theorem and I have no idea how to do one. Please help, it would be much appreciated. Here's what I have to go off of:

precal · Answer

angle f , f1 and B is an angle

precal · Answer

A, f1, E is the vertical angle

tw101 · Answer

These are my instructions:You may prove each theorem using either a two-column, paragraph, or flow chart proof. No matter the type of proof you choose, it must demonstrate a logical progression from one step to the next.

here is a link to a really good site that explains vertical angles. 

Hope it helps

precal · Answer

sorry Can't help with a proof. I have not done one is a very long time.  Look for one online and try to follow the same format

tw101 · Answer

@campbell_st  sorry, but there isnt a link there.

tw101 · Answer

@precal thats all right. Thanks for trying anyways.

campbell_st · Answer

the way to prove vertical angle theorem is to use the supplementary angle theorem

Well angle AEB looks like a right angle..

campbell_st · Answer

look at angle AEB in terms of supplementary angles

remember AEC is a line segment so therefore its a straight angle... 

so by definition angles ARB and BEC must add to 180..

precal · Answer

you can not assume right angles

precal · Answer

vertical angles do not have to be 90 degrees

campbell_st · Answer

oops again, should read angles AEB and angle BEC add to 180

tw101 · Answer

right

tw101 · Answer

but if it intersects at a line that equals 180, wouldnt it be 90?

tw101 · Answer

Im sorry this is all just a little new to me.

precal · Answer

supplementary angles mean any two angles that add up to 180
so you could have 2 angles say 10 + 170 equal 180  or 20 +160 equal 180

tw101 · Answer

Okay, so how exactly would I put that into a proof? I just dont know how to take the picture I have and turn it into that.

precal · Answer

we don't really need angle measurements to do a proof

tw101 · Answer

Okay, So how can I take the picture I posted with the vertical angles and turn it into one?

precal · Answer

I just googled "how to write a two column proof of a vertical angle"  Many videos came up and websites.  You need to read them but they are all basically saying the same thing.

tw101 · Answer

Will do. Thanks.

precal · Answer

Good luck but you really don't need angle measurements.  That is not how proofs are done.
