Question

The measures of some angles are given below. Write the type of each angle.

(1)	75°	(2)	0°
(3)	215°	(4)	360°
(5)	180°	(6)	120°
(7)	148°	(8)	90°

Answer 1

(i) An angle whose measure is less than 90^∘ is an acute angle.
(ii) An angle whose measure is 0^∘ is a zero angle.
(iii) An angle whose measure is bigger than 180^∘ but less than 360^∘ is a reflex angle.
(iv) An angle whose measure is 360^∘ is a complete angle.
(v) An angle whose measure is 180^∘ is a straight angle.
(vi) An angle whose measure is bigger than 90^∘ but less than 180^∘ is an obtuse angle.
(vii) An angle whose measure is bigger than 90^∘ but less than 180^∘ is an obtuse angle.
(viii) An angle whose measure is 90^∘ is a right angle.
