Parallel lines are lines that
are always the same distance
apart, and never meet.
A train needs to run on parallel lines, otherwise it wouldn’t be very safe!

Symmetry
This is a line of symmetry for a square. Notice that both halves of the square are exactly the same.
A line of symmetry is where a shape can be divided into two exact equal parts.
A line of symmetry can also be called a mirror line. Either side of the mirror line
looks exactly the same.
