Question: How many lines or symmetry and what order of symmetry does the shape to the right have.

Solution: To work out the lines of symmetry, you want to try drawing straight lines through the shape such that whatever is on one side of the line is a mirror image of what’s on the other side.

All possible lines of symmetry of this shape are:

Therefore, the number of lines of symmetry is 4.

As for the order of rotational symmetry, the question is: if you rotate the shape a full 360 degrees, how many times does it fit onto itself? Tracing paper is a great way to work this out.

Doing so, you would learn that the order of symmetry for this shape is 4.
