Solution:

We will use the concept of angles to solve this.
(a) Acute angle - It is less than 90°
(b) Obtuse angle - It is greater than 90° but less than 180°
(c) Right angle - It is equal to 90°
(d) Reflex angle - It is greater than 180° but less than 360°
(e) Straight angle - It is equal to 180°
(f) Acute angle - It is less than 90°
