Which term describes a polygon with four right angles?

• A. Parallel Lines
• B. Fact Family
• C. Symmetry
• D. Rectilinear Figure

Answer: (D)

Think about what four right angles means: a polygon where every corner is a 90-degree angle. A rectangle fits this description, and any polygon with straight sides that meet at right angles is called a rectilinear figure. So this term fits perfectly because it describes shapes with straight sides that form right angles. The other terms refer to unrelated ideas: parallel lines describe lines that never meet; a fact family is about arithmetic relationships; symmetry is about balanced, mirror-like halves. Rectilinear figure is the right category for a polygon with four right angles.
