How many lines of symmetry does this figure have?

In other words, how many lines of symmetry does this leaf have? Remember, a line of symmetry is the imaginary line where we could fold a shape and have each half match exactly.

So let’s take a closer look at the leaf. Can you see anywhere where we could fold the leaf in half? Let’s try this line right here.

If we were to fold the leaf along this line, we would see that each half fits exactly on top of the other. They’re an exact match. This line is also sometimes known as the mirror line.

If we were to place a mirror along this line of symmetry, the reflection would look like this. Each half matches exactly. So this is a line of symmetry. This is the only line of symmetry on this leaf.

So we can say that this figure has one line of symmetry. This is the only line where we could fold the shape and have each half match exactly.
