Which of the following figures can be divided into symmetrical halves?


a.
Figure 2
b.
Figure 4
c.
Figure 3
d.
Figure 1


Solution:


Figure 3 can be divided into symmetrical halves by drawing a horizontal line as shown.

Among the figures, Figure 3 can be divided into symmetrical halves.


Correct answer : (3)
 42.  
Identify the figure where the dotted line divides the figure into two symmetrical halves.


a.
Figure 2
b.
Figure 4
c.
Figure 3
d.
Figure 1


Solution:

Line of symmetry is a line that divides the figure into two equal parts.

Among the figures, the dotted line in the word 'V' in Figure 1 divides the word into two equal parts.

So, Figure 1 is the figure in which the dotted line divides the figure into two symmetrical halves.


Correct answer : (4)
 43.  
Identify the figure where the dotted line divides the figure into two symmetrical halves.

a.
Figure 4
b.
Figure 3
c.
Figure 1
d.
Figure 2


Solution:

Line of symmetry is the line that divides the figure into two parts, so that both parts match exactly on folding along the line.

Figure 1 is divided into two symmetrical halves by drawing a vertical line.

So, Figure 1 is divided into two symmetrical halves by the dotted line.


Correct answer : (3)
 44.  
Which of these figures has a dotted line that divides the figure into two symmetrical halves?

a.
Figure 3
b.
Figure 1
c.
Figure 4
d.
Figure 2


Answer: (b)


Correct answer : (2)
 45.  
Choose the figure that has a dotted line that divides the figure into two symmetrical halves.


a.
Figure 2
b.
Figure 3
c.
Figure 1
d.
Figure 4


Solution:

Line of symmetry is the line that divides the figure into two parts, so that both parts match exactly on folding along the line.

Figure 4 is divided into two symmetrical halves by drawing a vertical line.

So, Figure 4 has a dotted line that divides the figure into two symmetrical halves.


Correct answer : (4)
 46.  
Which of the figures is a reflection of Figure A?


a.
Figure 3
b.
Figure 2
c.
Figure 1
d.
Figure 4


Solution:

A reflection or flip is the transformation in which the figure is turned over.

When Figure A is turned over, Figure 2 is formed.

So, Figure 2 is the reflection of Figure A.


Correct answer : (2)
 47.  
Which of the figures is a reflection of Figure A?

a.
Figure 4
b.
Figure 1
c.
Figure 3
d.
Figure 2


Solution:

A reflection or flip is the transformation in which the figure is turned over.

When Figure A is turned over, Figure 1 is formed.

So, Figure 1 is the reflection of Figure A.


Correct answer : (2)
 48.  
Choose the figure that has a dotted line that divides the figure into two symmetrical halves.

a.
Figure 3
b.
Figure 4
c.
Figure 1
d.
Figure 2


Solution:

Line of symmetry is the line that divides the figure into two parts, so that both parts match exactly on folding along the line.

Figure 2 is divided into two symmetrical halves by drawing a vertical line.

So, Figure 2 has a dotted line that divides the figure into two symmetrical halves.


Correct answer : (4)
 49.  
Which of these figures has a line of symmetry?

a.
Figure 1
b.
Figure 2
c.
Figure 4
d.
Figure 3


Solution:

Line of symmetry is the line that divides the figure into two parts, so that both parts match exactly on folding along the line.

Among the figures, a vertical line drawn through Figure 3, divides it into two parts, which match exactly on folding along the line.

So, Figure 3 has a line of symmetry.


Correct answer : (4)
 50.  
Choose the figure that has a dotted line that divides the figure into two symmetrical halves.


a.
Figure 3
b.
Figure 4
c.
Figure 2
d.
Figure 1


Solution:

Line of symmetry is the line that divides the figure into two parts, so that both parts match exactly on folding along the line.

Among the figures, a vertical line drawn through Figure 2, divides it into two parts, which match exactly when folded along the line.

So, Figure 2 has a dotted line that divides the figure into two symmetrical halves.
