Figure 7:
- The figure is a quadrilateral with vertices E, M, N, P.
- A diagonal EN is drawn.
- The sides EM and NP are marked with single dashes, indicating EM = NP.
- The sides MN and EP are marked with double dashes, indicating MN = EP.
- Therefore, both pairs of opposite sides are equal in length.
- Additionally, the sides EM and NP are marked as equal, and MN and EP are marked as equal. This is the definition of a parallelogram.
- The diagonal EN divides the parallelogram into two congruent triangles (triangle EMN and triangle NEP).
Answer: Figure 7 represents a parallelogram, where both pairs of opposite sides are equal in length (EM = NP and MN = EP), and the diagonal EN divides it into two congruent triangles.
