(1)180^(@)quad " (a) Zero angle "

An angle of measure 180^(@) is called a zero angle (b) a right angle (c) a straight angle a reflex angle

An angle of measure 180^0 is called (a) a zero angle (b) a right angle (c) a straight angle (d) a reflex angle

In a Delta ABC angle A + angle B = 145^(@), 2 angle B + angle C = 180^(@) Find angle A and angle B

An angle whose measure lies between 180^(@) and 360^(@) is called a . . . . . . . . . . . angle.

The ratio of two angles is 3:1. Find the i) larger angle if the smaller is 180^@ , ii) smaller angle if the larger is 63^@ .

True or False: The measure greater than 180^(@) is a reflex angle.

An angle greater than 180^(@) and less than a complete angle is called _____________.
