1. The problem asks to identify the congruence criterion for the given figure labeled 27. 2. The figure is a kite-like shape split by a vertical segment from the top vertex to the middle bottom vertex. 3. The two upper slanted sides have matching tick marks, indicating they are congruent. 4. The two lower slanted sides also have matching tick marks, indicating they are congruent. 5. There is one marked angle at the lower left. 6. The congruence criteria options are: SSS, SAS, ASA, AAS, HL, or Not ≅. 7. Since the kite has two pairs of adjacent sides equal and one angle between them marked, this matches the SAS (Side-Angle-Side) criterion. Final answer: SAS
