HELP PLEASE!!! 2-column proof :(

OpenStudy (star_girl):

Given: Triangle ABC is equiangular. EF//AC Prove: Triangle EFB is equiangular. |dw:1419934438533:dw|

OpenStudy (ganpat):

If lines are parallel, then angles in matching corners are called Corresponding Angles. |dw:1419935825672:dw|

OpenStudy (ganpat):

R u still der ??

OpenStudy (star_girl):

@Ganpat yup sorry

OpenStudy (star_girl):

I know about corresponding angles

Directrix (directrix):

Statements ======= 1. Triangle ABC is equiangular. 2. m<A = m<B =m<C 3. Segment EF is parallel to Segment AC 4. <BEF is congruent to <BAC 5. <BCA is congruent to < BFE 6. Triangle ABC is similar to Triangle BEF 7. Triangle BEF is equiangular

Directrix (directrix):

These statements are the gist of the argument. I leave the reasons for you. @star_girl If you post the reasons, I or someone will try to check them for you.

OpenStudy (star_girl):

Thanks!! :D

Directrix (directrix):

You are welcome.

OpenStudy (star_girl):

Reasons ====== 1. given 2. definition of equiangular triangles 3. given 4. definition of congruent angle theorem 5. definition of congruent angle theorem I don't get 6 7. ??

@Directrix

OpenStudy (demonchild99):

if you log out and type the question your askin in google...it my come up with more openstudy questions like this...if you click on it you can become a phantom view like the dude/chick watching it right now...thats how i get help when no one is on

OpenStudy (star_girl):

@demonchild99 Thanks! I am going to try that. :D

Directrix (directrix):

These are in need of repair: 4. congruent angle theorem --> 4 and 5 have to do with a postulate and it's not congruent angle postulate 5. congruent angle theorem I don't get 6 --> Look up "postulate for triangle similarity" 7. ?? @star_girl
