Question 817965: Hi! How are you? I have a question pertaining to writing a proof.
This is what the figure looks like: http://imgur.com/1y9Jh6m
Given: Triangle ABF is congruent to triangle DFB, F is the midpoint of segment AE, and B is the midpoint of segment AC.
Prove: Triangle FDE is congruent to triangle BCD is congruent to triangle ABF (it's proving the three triangles are congruent to each other).
I tried it on my own, and I came up with the fact that, due to the definition of a midpoint, segment AF is congruent to segment FE and segment AB is congruent to segment BC.

The problem is, I'm not sure how to find out the other side or angle measures -- I'm stuck, and I don't know what to do next.
Thank you in advance for any and all help!

Question 821377: I have an image that is a Triangle with a line from the top angle to the middle line on the bottom:
Given: Line segment BD is perpendicular bisector of line segment AC
Prove: Line Segment BD bisects Angle ABC
I have tried to complete this task, but seem to be stuck on if I am doing so correctly and the right steps on how to achieve this proof.
Statement Reason
Angle BDA and Angle BDC are right angles. Definition of perp. lines.
Angle BDA is congruent to Angle BDC. Right Angle Theorem.
Line Segment AD is congruent to line segment DC. Definition of segment bisc.
Line segment BD is congruent to line segment BD. Reflexive Property.
Triangle ADB is congruent to triangle CDB. SAS.
Line segment AB is congruent to line segment CB. CPCTC.
Line segment BD bisects angle ABC. CPCTC.
I am unsure if I am correct in getting to this answer, as I tried to utilize all theorems and properties I could relate to this problem. Please help me fix where I am wrong, so I can accomplish my task.
Thanks
