Answers
Answer:
cute Angle:
An angle whose measure is more than 0° but less than 90° is called an acute angle. Angles having magnitudes 30°, 40°, 60° are all acute angles. In the adjoining figure, ∠X0Y represents an acute angle.
Acute Angle

∠X0Y < 90°
Right Angle:
An angle whose measure is equal to 90° is called a right angle. In the adjoining figure ∠ABC represents a right angle.
Right Angle

∠ABC = 90°
Obtuse Angle:
An angle whose measure is more than 90° but less than 180° is called an obtuse angle. In the adjoining figure, ∠XYZ represents an obtuse angle.
Obtuse Angle
9Save
∠XYZ > 90°
∠XYZ < 180°
Straight Angle:
An angle whose measure is equal to 180° is called a straight angle. In the adjoining figure, ∠XOY represents a straight angle.
Straight Angle
9Save
∠XOY = 180°
Reflex Angle:
An angle whose measure is more than 180° but less than 360° is called a reflex angle. In the adjoining figure, ∠POQ is a reflex angle. Angles having magnitudes 220°, 250°, 310° are all reflex angles.
Reflex Angle
9Save
∠POQ > 180°
∠POQ < 360°
Complete Angle:
An angle whose measure is equal to 360° is called a complete angle. In the adjoining figure, ∠BOA represents a complete angle.
60 minutes = 1 revolution = 1 complete angle.
