Question

given B is the midpoint of line CE, Angle C is congruent to angle E. prove angle a is congruent to angle D ​

Answer 1

Answer:

  see below

Step-by-step explanation:

The ASA congruence postulate is being invoked, so you're looking to show two angles and the side between them are congruent.

_____

Personally, I'd go at it differently. I'd say that alternate interior angles ∠C≅∠E means AE║CD, so ∠A≅∠D because they're alternate interior angles. B does not need to be a midpoint for this proof.
