Question

Classify the following angles as acute, obtuse, right and reflex angle. 90°, 125°, 35º, 65°, 80°, 120°, 135°, 210°, 270°, 150°, 20°, 45°, 135°, 150°, 165° a. Acute angle 90 b. Obtuse angle c. Right angle d. Reflex angle ​

Answer 1

Given:

Different angles are given to us which are  90°, 125°, 35º, 65°, 80°, 120°, 135°, 210°, 270°, 150°, 20°, 45°, 135°, 150°, 165°.

To Find:

We have to categorize these angles as  a. Acute angle 90 b. Obtuse angle c. Right-angled. Reflex angle ​

Step-by-step explanation:

• Acute angle- An angle which is less them 90° is known as acute angle.

• Obtuse angle- An angle which is greater them 90° is known as acute angle.

• Right angle- A 90° angle is right angle.

• Thus Acute angles are-35º, 65°, 80°, 20°, 45°

• Obtuse angles are- 120°, 135°, 150°, 135°, 150°, 165°.

• Right angle is- 90°
