Question

5) Choose what postulate proves the triangles congruent. *

SSS
SAS
AC bisects ZBAD, AC bisects ZBCD
ASA
AAS
A
HL
B
D

Answer 1

ASA (Angle-Side-Angle)

Line AC bisects angle BAD so the two angles left are congruent, the same with BCD.

Line AC is in both triangles

The line AC is between the two angles, so ASA.
