Problem 1Difficulty: Mastery
Which rule correctly decides whether an angle measure is reflex?
AThe measure is greater than 90° and less than 180°.
BThe measure is exactly 180°.
CThe measure is greater than 180° and less than 360°.
DThe measure is 360° or more.

Problem 2Difficulty: Mastery
A reflex angle leaves a 125° opening. What is the measure of the reflex angle?
Solution & Explanation:The reflex angle is the full turn minus the opening: 360° - 125° = 235°.
Problem 3Difficulty: Mastery
A reflex angle is about one-third of a full turn more than a straight angle. Which estimate is most reasonable?
A120°
B180°
C240°
D300°
Solution & Explanation:One-third of a full turn is 120°. Add that to a straight angle: 180° + 120° = 300°.
