Question 1: How many lines can pass through two different points?
A) many
B) only 2
C) only 1
D) no line
Explanation: Only 1 line can pass through two different points.
Question 2: If P, Q and R are collinear points, such that PQ = 11 cm, PR = 8 cm and RQ = 3 cm, then which point lies between the other two points?
A) R
B) P
C) Q

Question 3: The measure of a right angle is _________.
A) 90°
B) 60°
C) 45°
D) 180°
Explanation: The measure of a right angle is 90°.
Question 4: The measure of a straight angle is _________.
A) 90°
B) 180°
C) 360°
D) 270°
Explanation: The measure of a straight angle is 180°.
Question 5: Which of the following is an acute angle?
A) 90°
B) 80°
C) 95°
D) 180°
Explanation: Angles whose measures are less than 90° are called acute angles. Thus, 80° is an acute angle.
Question 6: Which of the following is an obtuse angle?
A) 85°
B) 60°
C) 100°
D) 89°
Explanation: Angles whose measures are more than 90° are called obtuse angles. Thus, 100° is an obtuse angle.
Question 7: What angle does a minute hand of a clock rotate in 15 minutes?
A) 180°
B) 90°
C) 60°
D) 30°
Explanation: In 15 minutes, the minute hand of a clock rotates through 90°.
Question 8: What angle does an hour hand of a clock rotate in 6 hours?
A) 30°
B) 60°
C) 90°
D) 180°
Explanation: In 6 hours, the hour hand of a clock rotates through 180°.
Question 9: Where will the minute hand of a clock stop if it starts at 2 and makes 1/3 of a revolution?
A) at 6
B) at 5
C) at 4
D) at 7
Explanation: In one revolution, the minute hand of a clock covers 12 numbers. So, in 1/3 revolution, the minute hand of the clock covers 1/3 × 12, that is, 4 numbers. Therefore, it will stop at 2 + 4, i.e. at 6.
Question 10: Which direction will you face if you initially face north and make 1/4 of a revolution clockwise?
A) south
B) west
C) east
D) north
Explanation: We will face east.
Question 11: How many right angles do you make if you start facing west and turn clockwise to south?
A) 2 right angles
B) 3 right angles
C) 1 right angle
D) 4 right angles
Explanation: We will make 3 right angles.
Question 12: Where will the hour hand of a clock stop if it starts from 8 and turns through two right angles?
A) at 1
B) at 2
C) at 3
D) at 4
Explanation: It will stop at 2.
Question 13: Which of the following is an example of a reflex angle?
A) 190°
B) 180°
C) 155°
D) 99°
Explanation: Reflex angles are greater than 180° but less than 360°. Therefore, 190° is an example of a reflex angle.
Question 14: Which of the following angles cannot be measured directly using a protractor?
A) Acute angles
B) Obtuse angles
C) Right angle
D) Reflex angles
Explanation: Since reflex angles measure more than 180°, and a protractor has markings till 180°, so, the reflex angles cannot be measured directly using a protractor.
Question 15: How many lines can pass through a single point?
A) 1
B) 2
C) infinite
D) 4
Explanation: An infinite number of lines can pass through a single point.
Question 16: Angle formed between two perpendicular lines measures ________.
A) 180°
B) 90°
C) 80°
D) 60°
Explanation: Angle between two perpendicular lines is 90°.
Question 17: Classify the triangle with sides 3 cm, 4 cm and 4.5 cm.
A) Scalene triangle
B) Isosceles triangle
C) Equilateral triangle
D) Right triangle
Explanation: Since the measure of the three sides are different, the triangle is a scalene triangle.
Question 18: Classify the triangle with angles 100°, 50° and 30°.
A) Acute-angled triangle
B) Right-angled triangle
C) Obtuse-angled triangle
D) Equilateral triangle
Explanation: Since one angle of the triangle measures more than 90°, it is an obtuse-angled triangle.
Question 19: How many faces are there in a pentagonal pyramid?
A) 5
B) 6
C) 10
D) 15
Explanation: A pentagonal pyramid has 6 faces.
Question 20: How many edges are there in a triangular prism?
A) 3
B) 6
C) 9
D) 4
Explanation: A triangular prism has 9 edges.
