Which angle is defined as greater than 180°?

• A. Straight angle
• B. Right angle
• C. Reflex angle
• D. Obtuse angle

Answer: (C)

A reflex angle is indeed defined as an angle that measures greater than 180 degrees but less than 360 degrees. This type of angle is often visualized as the larger "sweep" of a circle when compared to a straight angle, which measures exactly 180 degrees. In contrast, a straight angle is exactly 180 degrees, a right angle measures 90 degrees, and an obtuse angle measures between 90 degrees and 180 degrees. Understanding the characteristics of angles in such terms helps clarify their definitions and classifications. Hence, identifying a reflex angle as one exceeding 180 degrees is accurate and reinforces foundational concepts in geometry.
