Answer: To prove that triangles are congruent, we typically need additional information such as side lengths, angles, or congruent parts of the triangles (such as sides, angles, or both). Without this information, it is not possible to determine the congruence of the triangles or apply any specific postulate.
Step-by-step explanation: n the given question, a list of points A, B, P, C, and D is provided, but there is no specific information about the triangles formed by these points. Therefore, without additional information or context, it is not possible to identify a specific postulate that proves the triangles are congruent.
