Correct Answer:
D. Quadrilateral
This question pertains to basic geometry, specifically the classification of polygons based on their number of sides. A polygon is a closed two-dimensional shape made up of straight line segments.
The correct answer is Quadrilateral. The prefix "quadri-" means four, and "lateral" refers to sides. Therefore, a quadrilateral is any polygon that has exactly four sides and four vertices (corners). Examples include squares, rectangles, rhombuses, parallelograms, and trapezoids.
- Hexagon is a polygon with six sides. The prefix "hexa-" means six.
- Octagon is a polygon with eight sides. The prefix "octa-" means eight, as seen in an octopus having eight arms.
- Heptagon is a polygon with seven sides. The prefix "hepta-" means seven.
Knowing these prefixes helps in identifying and naming various polygons based on their fundamental properties, such as the number of sides and angles.
