If a line divides a given figure into two or more identical halves , then we say that the given figure is symmetrical about that line and the line is called the axis of symmetry or line of symmetry. Each one of the figures shown below is symmetrical about the dotted line and the dotted line is its line (or axis) of symmetry .
When a figure is folded along a line such a way that the two parts exactly fit on top of each other, then the figure is said to have a line symmetry. Line of symmetry is the line which divides figure into two identical parts and these are mirror image of each others.
It is not necessary that each figure has a line of symmetry or we cab say a figure may or may not have a line of symmetry .
We have two types of line of symmetry here :
In a figure if a vertical line divides it into identical parts, then line acts as an axis of the shape. Thus the axis which divides the shape into two identical halves, vertically, is called a vertical line of symmetry. The mirror image of the other half of the shape can be seen in a vertical or straight standing position. Some of the alphabets such as A, H, M, O, U, V, W, T, Y can be divided vertically in symmetry.
In a figure if a horizontal line divides it into identical parts, then line acts as an axis of the shape. Thus the symmetry line or horizontal axis of a shape which divides the shape into two identical halves is known as horizontal line of symmetry. That means the axis here crosses across the shape to cut it into two equal parts. The English alphabets such as B, C, H, E, are the examples of horizontal symmetry.
A figure having only one line of symmetry is known as as a figure with one line of symmetry.. This line of symmetry can be horizontal, vertical or can be align at any angle.

My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
Abhyas Methodology is very good. It is based on according to student and each child manages accordingly to its properly. Methodology has improved the abilities of students to shine them in future.
Abhyas is a complete education Institute. Here extreme care is taken by teacher with the help of regular exam. Extra classes also conducted by the institute, if the student is weak.
One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
Being a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.

I have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
