Notice how all the lines and patterns repeat on both the left and right sides of the page. Our second symmetry art coloring ...

We are fond of saying things are symmetric, but what does that really mean? Intuitively we have a sense of symmetry as a kind of mirroring. Suppose we draw a vertical line through the middle of a ...

Intuitively we have a sense of symmetry as a kind of mirroring. Suppose we draw a vertical line through the middle of a square. This line cuts the square into two equal parts, each of which is the ...

To most people, “symmetry” means the bilateral symmetry exhibited by, say, a butterfly, or the human face. That is, if you take a picture of a butterfly and draw a straight line down the ...

They all have vertical symmetry. This means you can draw a mirror line down through the middle of each shape and divide it into two reflected halves. Remember vertical means from top to bottom.

but we're going to talk about reflective symmetry. If you draw a line down something and the two sides are a reflection of each other, you have found the line of symmetry, or the mirror line.

In general usage, symmetry most often refers to mirror or reflective symmetry; that is, a line (in 2-D) or plane (in 3-D) can be drawn through an object such that the two halves are mirror images ...
