DEFINITION OF SYMMETRY A geometric shape or object is symmetric if it can be divided into two or more identical pieces that are arranged in an organized fashion. An object is symmetric if there is a transformation that moves individual pieces of the object but doesn't change the overall shape. The type of symmetry is determined by the way the
Some examples make this loose definition clearer. EXAMPLE 1: The rule that shifts each point of the plane two units in the positive y-direction is a mapping. This is an example of a mapping called a translation. In general … a translation is a mapping that shifts each point in the plane a fixed distance in a fixed direction.
Example. The best way to get a feeling for what an isometry looks like is to consider some examples. Identity : The identity is the function which simply takes a point P in the plane to the same point P. In other words, it does nothing, so hopefully you can see that it’s an example of an isometry — in fact, the simplest example of an isometry.

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 ...
1. Mathematical symmetry In common English usage, the term symmetry seems to have meant at first the property of being balanced or well-proportioned. This original meaning continues in a slightly more technical sense in the phrases bilateral symmetryand mirror symmetryapplied to a figure which looks the same as its image in a mirror. For example,
