**What is reflective symmetry?**

Reflective symmetry is more commonly known as Lines of Symmetry.

**What is a Line of Symmetry?**

Lines of symmetry are lines that can be drawn on a 2 dimensional shape where each side of the line is ** exactly** the same.

**Example: Are these lines of symmetry?**

The line of symmetry for the square is correct. Imagine that you could fold the shape at this number line, would the shape fit perfectly?

If It would, then you have a line of symmetry.

In the triangle, the shapes on either side of the line are not the same. This is **not a line **of symmetry.

**Example 2: How many lines of symmetry does the following shape have?**

This has two elements. The square and the letter A.

A square has 4 lines of symmetry, the letter A has one line of symmetry.

When we have two elements, the lower number of lines of symmetry is the one we use.

In this case, we have 1 Line of Symmetry.

**Example 3: How many lines of symmetry does the following shape have?**

This one is actually easier than the last one, this is a regular hexagon (remember: regular means all the angles and sides are the same.)

When we have a regular shape, the number of lines of symmetry is the same as the number of sides so this shape has 6 lines of symmetry
