Given: segment AC and segment BD bisect each other at E

prove: E is the midpoint of segment RS

i don't know if you will be able to visualize the picture but just incase someone is i really need help on the proof for this one.

Picture: two(supposedly congruent)triangles that intersect at one point(E). the first triangle is ABE and the second is DCE. point e(the place that both triangles meet) is intersected by a line RS that goes in the middle of the two triangles.

We are supose to prove that E is the midpoint of segment RS

if anyone is able to help me(i know it would kinda be impossible) but i would really appreciate it..

Thanks!
