Weekly Quiz Competition

Question 1
1 / -0

Which of the lines in the picture are lines of symmetry of the figure?

A
l, m and o

B
l and n

C
l, m, n and o

D
m and o

Solution

If you can reflect (or flip) a figure over a lime and the figure appears unchanged, then the figure has reflection symmetry or line symmetry. The line that you reflect over is called the line of symmetry. A line of symmetry divides a figure into two mirror-image halves.
In the given figure, lines $$l$$ and $$n$$ divide figure into two mirror-image halves.
Hence, they are lines of symmetries.
Question 2
1 / -0

The lines of symmetry of the given figure is/are

A
$$0$$

B
$$1$$

C
$$2$$

D
$$3$$

Solution

As shown in the figure, option B is correct.
Question 3
1 / -0

What is the smallest number of squares that must be shaded so that the figure has a line of symmetry?

A
$$1$$

B
$$3$$

C
$$5$$

D
$$7$$

Solution

Line of symmetry is defined as it divides the figure into two equal mirror halves.

Therefore total $$3$$ squares must be shaded so that the figure has a line of symmetry along its diagonal.

Hence the correct answer is option B.
Question 4
1 / -0

Which of the following dotted lines is a line of symmetry?

A
L

B
M

C
N

D
None of these

Solution

The line of symmetry divides the figure into two equal mirror halves.
$$\therefore$$ only dotted line N satisfies the above condition
Hence the correct answer is option C
Question 5
1 / -0

What is the least number of squares that must be added, so that the line AB becomes a line of symmetry?

A
$$1$$

B
$$2$$

C
$$3$$

D
$$4$$

Solution

Line of symmetry is defined as it divides the figure into two equal mirror halves.
So from the above figure minimum $$2$$ squares should be added so that line AB becomes a line of symmetry.
Hence the correct answer is option B
Question 6
1 / -0

In the given figure, which of the following is a line of symmetry?

A
Line B only

B
Line A and B

C
Line C

D
Line A and C

Solution

There is only one line of symmetry because Line B divide by figure into two parts equally.
Line B is a line of symmetry.
Question 7
1 / -0

Which of the following is a line of symmetry of the figure?

A
$$L$$ and $$O$$

B
$$L$$ and $$N$$

C
$$N$$

D
All $$L,\; M,\; N$$ and $$O$$

Solution

A line of symmetry is defined as the line which divides the figure into two equal mirror images
Hence from the above figure line $$L$$, line $$M$$, line $$N$$, line $$O$$ are the lines of symmetry.
Hence, the correct answer is option $$D$$.
Question 8
1 / -0

Complete the given figure on the basis of two lines of symmetry.

A

B

C

D

Solution

From the given figures, option A is correct.
Question 9
1 / -0

The number of lines of symmetry in an unsharpened pencil is/are

A
$$0$$

B
$$1$$

C
$$2$$

D
$$3$$

Solution

As shown in the figure, there are 2 lines of symmetry.
Hence, option C is correct.
Question 10
1 / -0

What is the smallest number of squares that must be added so that the line $$AB$$ becomes a line of symmetry?

A
$$1$$

B
$$2$$

C
$$5$$

D
$$4$$

Solution

Hence from the figure we can say that minimum $$5$$ number of squarss must be added , so that line AB will become line of symmetry.
Hence the correct answer is option C.
