Reflection Symmetry

If we place a mirror on the line of symmetry we can see the complete image. So, we find that the mirror image or reflection of the image in the mirror and the given figure are exactly symmetrical.

$Reflection Symmetry$

This type of symmetry is called reflection symmetry.

The mirror line is the line of symmetry between the two figures. The mirror image of an object is the same but it appears in the opposite direction.

$Mirror Line of Symmetry$

We note that the shapes in the above pictures are same but the other way round.

Definition of Order of Rotational Symmetry | Rotational Symmetry
The number of times a figure fits into itself in one complete rotation is called the order of rotational symmetry. If A° is the smallest angle by which a figure is rotated so that rotated from fits onto the original form, then the order of rotational symmetry is given
Line Symmetry | Vertical & Horizontal Lines of Symmetry | Symmetrical
We know that any object or shape which can be cut in two equal halves in such a way that both the parts are exactly the same is called symmetrical and the line which divides the shape in two equal halves is called the line of symmetry. A shape can have many lines of symmetry
What is Rotational Symmetry? | Centre of Rotation | Angle of Rotation
The shapes and objects that look the same after a certain amount of rotation are said to have rotational symmetry. Some shapes look the same after half a turn. If we turn English alphabet S around a centre point by 180° we get the alphabet S in the same position.
