Jester started to prove that the triangles below are congruent. He is only told that point is the midpoint of segments and .
![Two lines A, C and B, D intersect at point, E. Triangle A, B, ,E and D, C, E are formed.](https://s3-us-west-2.amazonaws.com/c3po-media-dev/files/cb19a720-259d-11e9-ab6b-d7741872f579/ccg_original.png)
Copy and complete his flowchart below. Be sure that a reason is provided for every statement.
