Question

Classify the following angles.

• A. (a) Acute angle (b) Obtuse angle (c) Right angle
• B. (a) Right angle (b) Acute angle (c) Obtuse angle
• C. (a) Right angle (b) Obtuse angle (c) Acute angle
• D. (a) Acute angle (b) Right angle (c) Obtuse angle

Answer 1

The correct option is A (a) Acute angle (b) Obtuse angle (c) Right angle



From the figure we can see that,
(a) Represents an angle which is less than 90°. So it is called acute angle.

(b) Represents an angle greater than 90°. Hence (b) is an obtuse angle.

From the figure, (c) represents an angle equal to 90°. Thus it is called right angle.

So (a) Acute angle (b) Obtuse angle (c) Right angle is the correct answer.
