Corresponding sides and sufficient congruence conditions

Answer: 4

1. The order gives A ↔ D and B ↔ E.
2. Therefore DE corresponds to AB
3. x=4cm.

Answer: Not enough information

1. Equal angles establish similarity, but do not establish equal size.
2. There is not enough information for congruence.

Answer: 7

1. The order gives A ↔ D and B ↔ E.
2. Therefore DE corresponds to AB
3. x=7cm.
