In triangle ABC and triangle DEF, AC is congruent to DE and <A is congruent to <E. Which of the following would allow you to conclude by SAS that these triangles are congruent ? a) side AB congruent to side DF
b) side AC congruent to side EF
c) side BA congruent to side FE
d) side CB congruent to side DF
Answer "C" is correct. because answer "A" side DF would not prove the triangles congruent. answer "B" side AC is already proven. And "D" is also incorrect because nether CB nor DF would prove the triangle congruent
