Answer: Option C. -> 16 cm2
:
C
The given figure is a square and XY is the line of symmetry.
Hence, AX=BX=2cm.
Therefore,AB=AX+BX
=2cm+2cm
=4cm
Since the length of one side is given we can determine its area enclosed by the formula Side x Side.
∴ The area of the square =4×4
=16cm2

Answer: Option A. -> True
:
A
Line of symmetry divides a figure into two equal halves in all aspects. Line of symmetry is the imaginary line where you could fold the image and have both halves matchexactly.

Answer: Option B. -> 2 cm
:
B
Since AD is the line of symmetry, the part of the figure to the right of this line is the reflection of the part of the figure to the left of it.
∴AB=AE=5cmandCA=FA=7cm.
Hence,
EF=FA−AE
EF=7−5=2cm

∴AB=AE=5cmandCA=FA=7cm.
Hence,
EF=FA−AE
EF=7−5=2cm
Answer: Option C. -> Left lower half and right upper half are not symmetrical.
:
C
All the parts of the car mentioned in the options are asymmetric. Even the right lower and left lower half because of the presence of the steering wheel in the left lower side.

Answer: Option B. -> Line of symmetry
:
B
When we are able to fold a picture in a half such that the left and right halves match exactly then we say that the picture has a line of symmetry.

Answer: Option B. -> 10 cm
:
B
The image formed in a plane mirror is of the same length of the object. So, the image of the line would remain a line and there would be no change in its length.
∴ refelction is a line of length 10cm.

Answer: Option A. -> Asymmetrical
:
A
Asymmetrical figures are those which do not have a line of symmetry and hence are not symmetrical. Asin the above figure, there is no line of symmetry,the given figure is asymmetrical.

Answer: Option B. -> There exist two different lines in the figure with respect to which the respective halves are mirror images of each other.
:
B
By two lines of symmetry we mean that two different lines in the figure can be drawn with respect to which the halves are mirror images of each other.
Eg. Rectangle, the alphabet 'X' etc.
