Symmetry is when a line is drawn through a shape to make one side of the line a reflection of the other. Symmetry is a property of 2D and 3D geometrical shapes and objects that divides them into two identical halves that mirror, or are mirror images of each other.
Three – Lines Symmetry. (iv) Examples of the shapes having four - lines symmetry: Four – Lines Symmetry. (v) Examples of the shapes having many - lines symmetry: Many – Lines Symmetry. The line which divides the shape into two equal parts from top to bottom is called the vertical line of symmetry.

A shape is said to be symmetric if it can be divided into two more identical pieces which are placed in an organized way. For example, when you are told to cut out a ‘heart’ from a piece of paper, you simply fold the paper, draw one-half of the heart at the fold and cut it out to find that the other half exactly matches the first half. The heart ca...
A vertical line of symmetry is that line that runs down vertically, divides an image into two identical halves. For example, the following shape can be split into two identical halves by a standing straight line. In such a case, the line of symmetry is vertical.
The horizontal line of symmetry divides a shape into identical halves, when split horizontally, i.e., cut from right to left or vice-versa. For example, the following shape can be split into two equal halves when cut horizontally. In such a case, the line of symmetry is horizontal.
A diagonal line of symmetry divides a shape into identical halves when split across the diagonal corners. For example, we can split the following squareshape across the corners to form two identical halves. In such a case, the line of symmetry is diagonal. A line of symmetry is an axis along which an object when cut, will have identical halves. The...
Figures with one line of symmetry are symmetrical only about one axis. It may be horizontal, vertical, or diagonal. For example, the letter "A" has one line of symmetry, that is the vertical line of symmetry along its center.
Figures with two lines of symmetry are symmetrical only about two lines. The lines may vertical, horizontal, or diagonal lines. For example, the rectanglehas two lines of symmetry, vertical and horizontal.
Figures with infinite lines of symmetry are symmetrical only about two lines. The lines may vertical, horizontal, or diagonal lines. For example, the rectangle has two lines of symmetry, vertical and horizontal. The following table shows the examples for different shapeswith the number of lines of symmetry that they have. Symmetry can be viewed whe...
If an object is moved from one position to another, with the same orientation in the forward and backward motion, it is called translational symmetry. In other words, translation symmetry is defined as the sliding of an object about an axis. For example, the following figure, where the shape is moved forward and backward in the same orientation by ...
When an object is rotated in a particular direction, around a point, then it is known as rotational symmetry, also known as radial symmetry. Rotational symmetry exists when a shape is turned, and the shape is identical to the origin. The angle of rotational symmetry is the smallest angle at which the figure can be rotated to coincide with itself an...
Reflective symmetry, also called mirror symmetry, is a type of symmetry where one half of the object reflects the other half of the object. For example, in general, human faces are identical on the left and right sides.
A Triangle can have 3, or 1 or no lines of symmetry: Quadrilaterals. Different types of Quadrilaterals (a 4-sided plane shape): Regular Polygons. A regular polygon has all sides equal, and all angles equal: An Equilateral Triangle (3 sides) has 3 Lines of Symmetry. A Square (4 sides) has 4 Lines of Symmetry. A Regular Pentagon (5 sides)
There are two types of symmetry: reflective and rotational. If a shape does not have symmetry it is called asymmetrical. Reflective symmetry can be seen in nature, such as with the...

Feb 1, 2010 · On the other hand, the third shape does not have the same kind of symmetry, because it has only two lines of reflection symmetry, and its smallest angle of rotation symmetry is 180°. Tilings. A tiling, also called a tessellation, is a covering of a flat surface by nonoverlapping shapes with no gaps between them.
