Anyone want to help me with my math homework? (Geometry)

Well, my question is basiclly, if ive got two congruent triangles, with corresponding angle bisectors, how do i prove the bisectors congrent?

If you could IM me on AIM (ViperMagic18) itd be great... if not ill be eagarly awaiting responces here...
 
how can CD be an agle bisector if there is no CD?
If it's not labeled I can't do your homework for you, which I might not even do anyway 🙂
 
CA congruent to DF

<c congruent <f

<a congruent to <d
Thats all given

Since c and f are congruent, their bisectors are congruent.

Then cag congruent to fdh because of ASA.

Then cg congruent to FH by cpctc

well, when I was in Geometry, it wasn't knowing that it was true, because most of the time it as grossly obvious, but the hard part is to prove it with these stupid laws and theorems that you had to explain every single thing you did. It was god awful.

Exactly!

Now, seeing as its 1:30, and as far as my body is concerned its 2:30, I'm off to bed. Thanks for the help, all!

Proofs were my favorite part of geometry 🙂
 
Oh come on, this is a very simple problem. In congruent triangles, all elements are equal. In particular, angle CAB = angle FDE, the sides AC and DF are also equal, and the angles ACD and DFH are equal because they are halfs of congruent angles. Therefore, the triangles ACD and DFH are congruent, and therefore the bisectors are congruent.
