Solution:
i) Straight angle is of 180° and half of a revolution is 180°. Hence. (i) – (c)
ii) Right angle is of 90° and one – fourth of a revolution is 90°. Hence, (ii) – (d)
iii) Acute angles are the angles less than 90°. Also, less than one fourth of a revolution is the angle less than 90°. Hence, (iii) – (a)
iv) Obtuse angles are the angles greater than 90° but less than 180°. Also between 1/4 and 1/2 of a revolution is the angle whose measure lies between 90° and 180°. Hence, (iv) – (e)
v) Reflex angles are the angles greater than 180° but less than 180° but less than 360°, Also more than half a revolution is the angle whose measure is greater than 180°.
Hence (V) ⟷ (b)
