What is a quadrant?

• A. One fourth of a circle.
• B. Half of a circle.
• C. A circle's center.
• D. A circle's circumference.

Answer: (A)

A quadrant is one quarter of a circle. It’s the sector created when you draw two radii from the center that are perpendicular to each other, dividing the circle into four equal parts, each spanning 90 degrees. So the quadrant corresponds to a quarter of the circle’s arc and area. That’s why the description “one fourth of a circle” is the correct choice. The other options describe the center (a point), the circumference (the outer boundary), or a semicircle (half of a circle), none of which define a quadrant.
