Question

I need help finishing the proof

Answer 1

Answer:

See proof

Step-by-step explanation:

      Statements                  Reasons

1. $\overline{AEC}$ bisects $\angle DAB,\ \angle 1\cong \angle 2$   Given

2. $\angle 3\cong \angle 4$                Definition of angle bisector

3. $\overline{AE}\cong \overline{AE}$                Reflexive property of equality

4. $\triangle ABE \cong \triangle ADE$               AAS postulate

5. $\overline {AB}\cong \overline{AD}$             Congruent triangles have congruent corresponding sides

6. $\overline{AC}\cong \overline{AC}$                Reflexive property of equality

7. $\triangle BAC \cong \triangle DAC$                   SAS postulate

8. $\overline {BC}\cong \overline{CD}$             Congruent triangles have congruent corresponding sides
