(a) E

(b) O

(c) T

(d) N

Answer: (b) O

Q2. After what fraction of a full turn does a basic windmill (firki) look the same again?

(a) 1/3

(b) 1/4

(c) 1/2

(d) 1

Answer: (b) 1/4

Q3. Which number among the following has both rotational and reflection symmetry?

(a) 8

(b) 7

(c) 4

(d) 1

Answer: (a) 8

2. Very Short Answer (VSA).

Q4. What is reflection symmetry?

Answer: Reflection symmetry means one-half of a figure is the mirror image of the other half, divided by a line called the line of symmetry.

Q5. Name one letter that has only a vertical line of symmetry.

Answer: The letter “A” has only a vertical line of symmetry.

Q6. Which traditional art form is famous for symmetrical block printing in Rajasthan?

Answer: Block printing is known for creating symmetrical designs in Rajasthan.

3. Short Answer Questions.

Q7. Describe the steps to make a paper cutout of the letter ‘H’ using symmetry.

Answer: To make a cutout of ‘H’:

1. Fold the paper vertically, then horizontally, making one-fourth of the paper.
2. Draw one-fourth of the letter ‘H’ along the fold.
3. Cut the outline, open to reveal ‘H’ with both vertical and horizontal symmetry.

Q8. Explain why a firki (windmill) shows rotational symmetry using an example.

Answer: A firki has four blades arranged equally. When rotated by 1/4 of a turn (90 degrees), it looks the same as before. So, it shows rotational symmetry at every quarter turn, making it symmetrical with respect to rotation.

Q9. Give two examples of numbers which have both rotational and reflection symmetry.

Answer: The numbers 0 and 8 have both rotational and reflection symmetry. This means they look the same when turned upside down and have a line dividing them into two identical mirror halves.

Q10. Differentiate between reflection symmetry and rotational symmetry with an example.

Answer: Reflection symmetry means the two parts of an object are mirror images across a line (e.g., letter A). Rotational symmetry means the object looks the same after rotating it by a certain angle (e.g., firki after a quarter turn).

4. True or False Questions.

Q11. The letter ‘N’ has both vertical and horizontal lines of symmetry.

Answer: False

Q12. Block printing designs are often symmetrical.

Answer: True

Q13. If a shape looks the same after a 1/2 turn, it has rotational symmetry.

Answer: True

Q14. The digit ‘7’ has reflection symmetry.

Answer: False

3. Fill in the Blanks Questions.

Q15. The line that divides a shape into two identical mirror halves is called the _________ of symmetry.

Answer: line

Q16. A firki (windmill) shows symmetry at every _________ turn.

Answer: one-fourth (1/4)

Q17. Traditional block printing is a craft of _________.

Answer: Rajasthan

Q18. Numbers such as 0 and 8 have _________ and _________ symmetry.

Answer: rotational, reflection
