(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 \(\frac{1}{4} \) and \(\frac{1}{4} \) of a revolution
(f) One complete revolution

(i) Straight angle \(\rightarrow \) (c) Half of a revolution.
(ii) Right angle \(\rightarrow \) (d) One-fourth of revolution.
(iii) Acute angle \(\rightarrow \) (a) Less than one-fourth of a revolution.
(iv) Obtuse angle \(\rightarrow \) (e) Between 14 and 12 of a revolution.
(v) Reflex angle \(\rightarrow \) (f) One complete revolution, right, acute, obtuse or reflex.
