Acute Angle: An angle whose measure up is more than 0° however less 보다 90° is referred to as an acute angle. Angles having magnitudes 30°, 40°, 60° space all acute angles. In the adjoining figure, ∠X0Y to represent an acute angle.
You are watching: An angle whose measure is 180
An angle whose measure up is same to 90° is dubbed a ideal angle. In the adjoining number ∠ABC represents a right angle.
∠ABC = 90°
Obtuse Angle: An angle whose measure up is more than 90° yet less than 180° is referred to as an obtuse angle. In the adjoining figure, ∠XYZ to represent an obtuse angle.
∠XYZ > 90°∠XYZ
Straight Angle: An angle whose measure is equal to 180° is called a straight angle. In the adjoining figure, ∠XOY represents a straight angle.
∠XOY = 180°
Reflex Angle: An edge whose measure is more than 180° however less 보다 360° is referred to as a reflex angle. In the adjoining figure, ∠POQ is a reflex angle. Angles having actually magnitudes 220°, 250°, 310° are all reflex angles.
∠POQ > 180°∠POQ
Complete Angle: An edge whose measure up is equal to 360° is dubbed a complete angle. In the adjoining figure, ∠BOA represents a finish angle. 60 minutes = 1 transformation = 1 complete angle.
