Which statement about a hexagon best matches the source material?

• A. A closed figure with six equal sides.
• B. A closed figure with six sides.
• C. A polygon with seven sides.
• D. A closed figure with six equal sides.

Answer: (D)

A hexagon is defined by a closed figure with six sides, and when the source material specifies that all six sides are equal, it’s describing a regular hexagon. The statement that matches this most precisely includes both the six-sided constraint and the equality of all sides, giving a complete description of a regular hexagon. The other ideas either describe a figure with seven sides, which isn’t a hexagon, or describe six sides without asserting equality, which is less specific and doesn’t align with the material’s emphasis on equal sides.
