When you hear the word symmetry, you might think generally of triangles, butterflies, or even ballerinas. But defined scientifically, symmetry is “a transformation that leaves an object unchanged.”. Huh? Colm Kelleher unpacks this abstract term and explains how animals' distinct symmetries can tell.

The simplest symmetry is Reflection Symmetry (sometimes called Line Symmetry orMirror Symmetry). It is easy to see, because one half is the reflection of the other half. The reflection in this lake also has symmetry, but in this case: 1. the Line of Symmetryruns left-to-right 2. it is not perfect symmetry, as the image is changed a little by the la...
With Rotational Symmetry, the image is rotated (around a central point) so that it appears 2 or more times. How many times it appears is called the Order. Here are some examples (they were made using Symmetry Artist, and you can try it yourself!)
Point Symmetryis when every part has a matching part: 1. the same distancefrom the central point 2. but in theopposite direction. It is also the same as "Rotational Symmetry of Order 2"above
5 days ago · Symmetry describes when several parts of an object are identical, such that it's possible to flip, spin, and/or move the object without ultimately changing what it looks like. Symmetry is extremely powerful and beautiful problem-solving tool and it appears all over the place: in art, architecture, nature, and all fields of mathematics! The three basic kinds of 2-dimensional symmetry are ...

Simply Symmetry. Join teacher Amanda as we discuss symmetry. There's symmetry all around us- in nature, in our homes, in words, in numbers, and in art. We examine various shapes and talk about vertical, horizontal and diagonal lines of symmetry. Apples, Adjectives and Animals - Oh My!
