1. Which instrument is used to measure angles accurately?
Answer: C) Protractor
Explanation: A protractor is specially designed to measure angles in degrees.
Explanation: A protractor is specially designed to measure angles in degrees.
2. An angle smaller than a right angle is:
Answer: B) Acute
Explanation: Acute angles measure less than 90°.
Explanation: Acute angles measure less than 90°.
3. Which angle is greater: 60° or 90°?
Answer: B) 90°
Step‑by‑step: Compare numbers → 90 > 60 → So 90° is greater.
Step‑by‑step: Compare numbers → 90 > 60 → So 90° is greater.
4. A right angle measures:
Answer: C) 90°
5. Which is the largest angle?
Answer: C) 120°
Explanation: Compare values → 120° is greatest.
Explanation: Compare values → 120° is greatest.
6. An angle of 150° is:
Answer: C) Obtuse
Step: 90° < 150° < 180° → Obtuse.
Step: 90° < 150° < 180° → Obtuse.
7. Estimate the angle in a corner of a book:
Answer: C) 90°
Explanation: Book corners form right angles.
Explanation: Book corners form right angles.
8. Which is smaller?
Answer: C) 85°
Comparison shows 85° is least.
Comparison shows 85° is least.
9. An angle greater than 180° is:
Answer: B) Reflex
10. Which is closer to a straight angle?
Answer: A) 160°
Straight angle = 180°. 160° is nearest.
Straight angle = 180°. 160° is nearest.
11. Half of a right angle is:
Answer: B) 45°
Step: 90° ÷ 2 = 45°.
Step: 90° ÷ 2 = 45°.
12. Double of 40° equals:
Answer: B) 80°
40° × 2 = 80°.
40° × 2 = 80°.
13. Which pair forms a right angle when combined?
Answer: A) 30° & 60°
Step: 30 + 60 = 90°.
Step: 30 + 60 = 90°.
14. Three right angles equal:
Answer: B) 270°
15. Which angle is obtuse?
Answer: B) 95°
16. Estimate the angle between clock hands at 3:00:
Answer: B) 90°
17. The largest acute angle possible is:
Answer: A) 89°
18. Which is nearer to 0°?
Answer: C) 5°
19. An angle equal to a straight angle is:
Answer: C) 180°
20. If one angle is 30° and another is 70°, which is greater?
Answer: B) 70°
Step: Compare numbers → 70 > 30.
Step: Compare numbers → 70 > 30.
