Answer:
3. a.Different Types of Angles
Acute Angles.
Right Angles.
Obtuse Angles.
Straight Angles.
Reflex Angles.
Complete Angle.
b.
Acute 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.
Right Angle:
An angle whose measure is equal to 90° is called a right angle. In the adjoining figure ∠ABC represents a right angle.
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.
Straight Angle:
An angle whose measure is equal to 180° is called a straight angle. In the adjoining figure, ∠XOY represents a straight angle.
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.
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.
