Match the following:
(i) Straight angle      (a) Less than one-fourth of a revolution.
(ii) Right angle         (b) More than half a revolution.
(iii) Acute angle        (c) Half of a revolution.
(iv) Obtuse angle     (d) One-fourth of a revolution.
(v) Reflex angle       (e) Between ¼ and ½ of a revolution.
                                 (f) One complete revolution.

Solution:

We will use the concept of angles to solve this.

Match the following angles to the meaning.
(i) Straight angle ↔ (c) Half of a revolution.
(ii) Right angle ↔ (d) One-fourth of a revolution.
(iii) Acute angle ↔ (a) Less than one-fourth of a revolution.
(iv) Obtuse angle ↔ (e) Between ¼ and ½ of a revolution.
(v) Reflex angle ↔ (b) More than half a revolution.
