The provided image contains three geometric diagrams. Please analyze each diagram and describe its key features and any labeled points or lines.

Here's an analysis of each geometric diagram:

• Diagram 1: This diagram shows a prism with a triangular base. The vertices of the base are labeled A, B, and C, and the corresponding vertices of the top face are labeled A1, B1, and C1. Points M, K, and N are also marked on the diagram. M is on the edge AA1, K is inside the prism, and N is on the edge B1B.
• Diagram 2: This diagram appears to show two separate planes or rectangular faces, possibly as part of a projection or unfolding of a 3D shape. The first plane has vertices labeled A, B, A2, and B1. Points M and K are marked on this plane. The second plane has vertices labeled D, C, D1, and C1, with point N marked on it. The dashed lines suggest connections or alignments between these planes.
• Diagram 3: This diagram illustrates a hexagonal prism. The vertices of the bottom base are labeled A, B, C, D, and N (possibly indicating a vertex or a point on an edge), and the corresponding vertices of the top face are labeled A1, B1, C1, D1, E1, and F1. Points M, K, F, and E are also marked. M is on the face A1B1C1, K is on the base ABCD, F is on the edge A1F1, and E is on the edge D1E1.
