Question 1. On her way to meet her friends, Sonali saw an ambulance and wondered as to why the word 'ambulance ' is written in the manner depicted in the image? Choose the correct option explaining the reason.

To confuse other vehicle drivers.
To scare other vehicle drivers.
To be viewed properly when seen in a rear view mirror.
Just for fun

Discuss Question

Answer: Option C. -> To be viewed properly when seen in a rear view mirror.
:
C
The manner in which "ambulance "is written is actually the mirror image of the word. This, when viewed in a rear view mirror appears straight in the manner we read. Therefore making it easier for ambulance to be identified and make its way in traffic.

Question 2. A boy was cutting paper with scissors; he suddenly looked at scissors and thought that it might have symmetry. Which of the following options correctly shows the line of symmetry?

Discuss Question

Answer: Option C. -> To be viewed properly when seen in a rear view mirror.
:
A
Line of symmetry is a line with respect to which the two halves are mirror images of each other. We see that in the correct option, the line acts as a line of symmetry as the halves are mirror images of each other with respect to that line.

Question 3. How many lines of symmetry does the regular hexagon shown below have?

Two
Four
Six
Zero

Discuss Question

Answer: Option C. -> Six
:
C

It is clear from the above figure that a regular hexagonhas six lines of symmetry.

Question 4. (a) State whether L is the line of symmetry or not assuming that the thickness of the pizza is negligible? [2 MARKS]

(b) How many lines of symmetry are possible for this figure?

Discuss Question

:
Each option: 1 Mark
(a) Yes, L is the line of symmetry as it divides the pizza into two identical parts.
(b)We can have only one line of symmetry for this figure.

Question 5. Which of the following represents a symmetrical figure? [1 MARK]

Discuss Question

:
If a figure can be folded or divided in such a waythat the two halves match exactly, such a figure is called a symmetrical figure.
In the given options, the image of the butterfly is the only one which can be divided into two symmetrical halves.

Question 6. While reading about symmetry, Sonali came across that the letters X, V and M have point symmetry. Predict whether what she read was true or false.

True
False
To be viewed properly when seen in a rear view mirror.
Just for fun

Discuss Question

Answer: Option A. -> True
:
A
Point symmetryoccurs when there exists a position or a central point on an object such that central point splits the object or shape into two parts, every part on each has a matching part on the other that is the same distance from the central point and both parts face different directions. The alphabets 'X', 'V' and 'M' exhibit point symmetry and are depicted as follows.

Question 7. Given below is a list of statements explaining the symmetry of letters from A-Z. Choose the correct option with reference to these statements.
Statement 1: All letters are symmetrical.
Statement 2: All letters have vertical line of symmetry.
Statement 3: All letters have horizontal line of symmetry.
Statement 4: All letters are asymmetrical.

Statement 1 is incorrect.
Statements 1 and 2 are incorrect.
Statements 1, 2 and 3 are incorrect.
Statements 1, 2, 3 and 4 are incorrect.

Discuss Question

Answer: Option D. -> Statements 1, 2, 3 and 4 are incorrect.
:
D

Question 8. The front and back of a car are asymmetrical.

True
False
To be viewed properly when seen in a rear view mirror.
Just for fun

Discuss Question

Answer: Option A. -> True
:
A
The front and backof a car are different from each other in many aspects.

1,2, 3 & 4

Discuss Question

Answer: Option D. -> 1,2, 3 & 4
:
D

Question 10. Sonali's best friend name starts with the letter 'H'. She was working out the lines of symmetry in 'H'. Which of the following statements for letter H is/are correct.
Statement 1: It has only a horizontal line of symmetry.
Statement 2: It has only a vertical line of symmetry.
Statement 3: It has both a horizontal and a vertical line of symmetry.
Statement 4: It is asymmetrical.

Only statement 2 is correct.
Statement 4 is correct.
Statement 3 is correct.
Only statement 1 is correct.

Discuss Question

Answer: Option C. -> Statement 3 is correct.
:
C
The letter H has two lines of symmetry. One horizontal and one vertical as depicted in the image below. If the letter H is folded about any of these lines the two parts will overlap each other completely.
