Question 740751:
Hi!I am sooo stuck with this two column proof: Given angle BAC is a right angle, angle DEC is a right angle, DB bisects AE, Prove C is the Midpoint of DB. Can you help? I know the triangles are congruent , but not sure if it is by AAS, and is one of the steps verticle angles, are congruent, or just alt interior angles?

angle BAC=angle DEC = 90 given
Angle BCA= angle DCE = vertically opposite angles
AC congruent CE ( given)
( BD bisects AC)
AAS Test
