Show transcript
When you fold a shape on a line of symmetry, the two halves will match exactly.
A line of symmetry is not always horizontal or vertical.
Some quadrilaterals, such as a parallelogram, have no lines of symmetry.
Others, such as a kite, have one line of symmetry. Others, such as a rectangle, can have more than one line of symmetry.
