Match the following: (i) Straight angle (a) Less than one-fourth of a revolution (ii) Right angle (b) More than half of revolution (iii) Acute angle (c) Half of a revolution (iv) Obtuse angle (d) One-fourth of a revolution (v) Reflex angle (e) Between 1 4 and 1 2 of a revolution

We have, Straight angle is 180 ° and one complete revolution is 360 ° Now, 180 ° 360 ° = 1 2 Therefore, straight angle is half of revolution. Right angle is 90 ° and 90 ° 360 ° = 1 4 Therefore, right angle is 1 4 of revolution. Acute angle is an angle between 0 ° to 90 ° . Therefore, it implies less than one-fourth of a revolution. Obtuse angle is an angle between 90 ° to 180 ° and 180 ° 360 ° = 1 2 Therefore, it implies between 1 4 and 1 2 of a revolution. Reflex angle is an angle greater than 180 o . Thus, it implies more than half a revolution. Hence, the completed table is as follows: (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 1 4 and 1 2 of a revolution (v) Reflex angle (b) More than half of a revolution
