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?

You can put this solution on YOUR website!
angle BAC=angle DEC = 90 given
Angle BCA= angle DCE = vertically opposite angles
AC congruent CE ( given)
( BD bisects AC)
AAS Test
