Look at the figures below and write the type of each of the angles.

(a) An angle whose measure is less than 90^∘ is an acute angle.
(b) An angle whose measure is 90^∘ is a right angle.
(c) An angle whose measure is bigger than 180^∘ but less than 360^∘ is a reflex angle.
(d) An angle whose measure is 180^∘ is a straight angle.
(e) An angle whose measure is 0^∘ is a zero angle
(f) An angle whose measure is 360^∘ is a complete angle.
