## What Is Symmetry? A Definition for Kids

If you're looking to introduce your lesson by explaining what symmetry is, this kid-friendly definition of the geometry concept may help!

Symmetry is when something is exactly the same on both sides. Think of it like a mirror — if you were to draw a line down the middle, both sides would be identical.

If a shape cannot be split in this way, we call it asymmetrical.

## What Is the Line of Symmetry? A Definition for Kids

Of course, one of the key concepts of any symmetry lesson plan is learning about the line of symmetry — what it is and how to find it. Here's one way to explain it to your students!

The line of symmetry is like an imaginary line that cuts something in half so that both sides are exactly the same. It is also called the axis of symmetry.

The line of symmetry of a shape is based on its orientation, meaning that the line that splits an object into two perfectly matched halves can appear differently — depending on the shape.

Shapes can have any of the following:

- Vertical Line of Symmetry
- Horizontal Line of Symmetry
- Diagonal Line of Symmetry

## How to Find the Line of Symmetry

To find the line of symmetry, have your students fold an object such as a piece of notebook paper in half or draw a line down the middle to see if both sides match.

For example, if they have a square, students can draw a line from one corner to the opposite corner to find the line of symmetry. You can also have students draw heart shapes — or use a printed heart template — and fold it in half to find the Y-axis that splits the two halves of the heart.

Once they find the line of symmetry, students can use it to create symmetrical patterns or designs!

## Different Types of Symmetry

There are several different types of symmetry that students will learn about throughout primary school.

### Line Symmetry or Reflexive Symmetry

Line symmetry — also called reflexive symmetry — describes when something is exactly the same on both sides of a line. It's a bit like a magic trick that makes things look exactly the same on both sides of a line, and it's a fun way to make art and designs — if you were to put colourful paint on one side of a piece of paper, then fold the paper in half while the paint is still wet, you would have a beautiful piece of art that has line symmetry.

To explain this to students, you might want to use the example of a butterfly.

Imagine you have a butterfly that has the same shape and pattern on both sides of its body. That means that the butterfly has line symmetry! If you were to draw a line down the middle of the butterfly's body, both sides would match up perfectly.

### Rotational Symmetry

If you can keep rotating an object around, and it will always look the same after 60 degrees, 120 degrees, 180 degrees, and so on, that means it has rotational symmetry! Some shapes that have rotational symmetry include squares, circles, equilateral triangles and hexagons.

Rotational symmetry is a bit like spinning a toy around and around and seeing if it looks the same from all angles. Imagine if you have a toy car with a circle on it. If you spin the car around, you'll see that the circle looks the same in every direction. This means that the circle has rotational symmetry.

### Translational Symmetry

Translational symmetry is when something looks exactly the same no matter where you move it. Kids might think of this type of symmetry as like a sliding game that makes things look the same no matter where you move them.

To use the toy car example from above, imagine if you took that toy car and you slid it to the left or right. The car would look exactly the same in every position along the way. This means that the car has translational symmetry.

### Glide Symmetry

Glide symmetry is like a sliding and flipping game that makes things look the same no matter how you move them.

Let's go back to the butterfly for this one. Say you have a butterfly with its wings spread out. If you slide the butterfly to the left or right and then flip it over, the butterfly will look the same as it did before. This means that the butterfly has glide symmetry!
