Point symmetry occurs 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.

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.

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.
$\therefore$ The area of the square $=4\times 4$
                                          $=16{\text{cm}}^2$

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.

The front and back of a car are different from each other in many aspects.

Out of 26 letters some are symmetrical while some are not symmetrical. Among the symmetrical letters some have vertical while some have horizontal lines of symmetry.

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.
$\therefore AB=AE=5cm\text{and}CA=FA=7cm.$
Hence,
$EF=FA-AE$
$EF=7-5=2cm$

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.

If a figure is equally balanced in proportion then it said to be symmetrical.

The letter A is symmetric and it has one line of symmetry.

But letters 'F', 'G' and 'L' have no lines of symmetry.
