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 know that, Straight angle is 180 o and one complete revolution is 360 ° . Therefore, straight angle is half of revolution. We know that, Right angle is 90 o and 90 ° 360 ° = 1 4 Therefore, right angle is 1 4 of revolution. Acute angle is an angle that lies between 0 o to 90 o . Therefore, it implies less than one-fourth of a revolution. Obtuse angle is an angle that lies between 90 o to 180 o 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 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
