Answer:
Step-by-step explanation:
1)AB = XY, BC = YZ, and angle B Â is congruent to angle Y
Answer:  ΔABC and ΔXYZ are congruent by  the SAS criterion
2)AB = XY; angles A and B are  congruent to angles X and Y  respectively.
Answer: ΔABC and ΔXYZ are congruent by  the ASA criterion.
3) AB = XY, BC = YZ, and CA = ZX
Answer: ΔABC and ΔXYZ are congruent by  the SSS criterion.
4)Angles A, B, and Care congruent  to angles X, Y, and Z, respectively.
Answer: ΔABC and ΔXYZ are not necessarily congruent.
