What is symmetry?
A 2D shape is symmetrical if a line can be drawn through it and either side is a reflection of the other.
The line is called a line of symmetry.
This is sometimes called a 'mirror line' or 'mirror symmetry', because if you put a mirror on the line, the reflection would show the whole shape.
Watch: How do you find lines of symmetry?
