- 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.

Reflection and Symmetry. Line symmetry and the mirror reflection are naturally related and linked to each other. Look at the picture showing the reflection of English letter L. The object and its image are symmetrical with reference to the mirror line.
If the folds do not match up entirely, the figure is asymmetric. For example a triangle can either have three (equilateral), one (isosceles), or no (scalene) lines of symmetry. These worksheets explains how to recognize and apply symmetry.

In mathematics, especially in geometry and its applications, an object is said to have symmetry if it can be divided into two identical halves. For example, look at the given picture of a flower: If we were to draw an imaginary line in the middle of it, we could divide it into two equal parts like this: Note that the two parts are identical and mir...
Let’s look at this flower again, the dotted line along which we divided it into two identical halves is called the line of symmetry or the axis of symmetry. It can also be defined as the line along which we can fold the object and its left and right half would completely overlap with each other. In mathematics, there are three types of lines of sym...
Symmetry was taught to humans by nature itself. A lot of flowers and most of the animals are symmetric in nature. Inspired by this, humans learned to build their architecture with symmetric aspects that made buildings balanced and proportionate in their foundation, like the pyramids of Egypt! We can observe symmetry around us in many forms: 1. Tree...
Example 1: How many lines of symmetry does the given figure have? Answer: Only one line of symmetry. Example 2: Can you find any examples of letters from the alphabet that have a horizontal line of symmetry? Answer: A lot of letters, like O, D, H, have horizontal lines of symmetry. Example 3: Is the given shape symmetric or asymmetric? Answer: The ...
Symmetry is when a line is drawn through a shape to make one side of the line a reflection of the other. It is a property of a 2D polygon or 3D polyhedron. There are two different types of symmetry that you need to be aware of: lines of symmetry and rotational symmetry.
