That means if you were to fold the paper along the line of symmetry, both halves would match perfectly. Line of SymmetryĪ line of symmetry is a line that divides a figure into two halves that are mirror images of each other. A simple example of this would be a checkerboard, which has translational symmetry across both its rows and columns. Translational symmetry is when an object looks the same after being translated (moved) in a certain direction. A classic example of this is a snowflake, which has six-fold rotational symmetry. Rotational symmetry is when an object looks the same after being rotated about a point. An example of this would be a butterfly, which has reflectional symmetry across its center. Reflectional symmetry is when an object looks the same after being reflected over a line or plane. There are three types of symmetry: reflectional, rotational, and translational. In other words, an object is symmetrical if it looks the same after being rotated or mirrored. In mathematics, symmetry can be defined as a transformation that doesn’t change the appearance of an object. Symmetry is found in many places in nature and everyday life. It would look the same if you reflected it over the x-axis. An example of reflection symmetry would be a vertical line on a graph. Reflection symmetry is when an object is flipped over a line without being turned or moved. It would look the same if you rotated it by any angle. An example of rotation symmetry would be a circle. Rotation symmetry is when an object is turned around a point without being flipped or moved. It would look the same if you shifted it to the left or right. An example of translation symmetry would be a line on a graph. Translation symmetry is when an object is moved without being turned or flipped. There are three types of symmetry: translation, rotation, and reflection. So, if an object is symmetrical, it will look the same after the transformation. ![]() Many artists and architects use symmetry in their work to create pleasing compositions. Symmetry is not only found in nature, but also in art and architecture. An example of this would be a spiral shell or a snowflake. Rotational symmetry occurs when an object can be rotated and still look the same. An example of this would be a human face or a butterfly. Bilateral symmetry occurs when an object can be divided into two identical halves down the middle. Radial symmetry occurs when an object can be divided into identical sections around a central point. There are three types of symmetry that can be found in nature: radial, bilateral, and rotational. Informally, this means that if you were to fold a piece of paper in half, both halves would look exactly the same. ![]() In this blog post, we will explore these different types of symmetry in more depth and provide examples for each. Other types of symmetry include rotational symmetry, translational symmetry, and scale invariance. The most common type of symmetry is reflectional symmetry, which is when an object is reflected across a line or plane. There are many different types of symmetry, each with their own name and properties. If you were to take a shape and reflect it across a line, the two resulting shapes would be symmetrical. ![]() What is Symmetry Definitions and Examples
