Write down the name given to each of the following angles.
a)
b)
d)

a) right-angle

b) acute angle

c) obtuse angle

d) reflex angle

A=right angle, the square indicates that the angle is 90 degrees (a right angle)

B=Acute angle, the angle is smaller than a right angle and therefore is an acute angle

C=Obtuse angle, given that the angle is greater than 90 degrees but smaller than 180 the angle is obtuse

D=Reflex angle, given the angle is larger than 180 degrees (straight) but hasnt completed a full circle it is a reflex angle
