Square
- A square has rotational symmetry of order 4. This is because it can be rotated four times (90°, 180°, 270° and 360°) and still look the same.

Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.

You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry. Here I have folded a rectangle one way, and it didn't work .
Lines of symmetry are straight lines that divide a shape into two equal parts where one part is an exact reflection of the other. E.g. A rectangle has two lines of symmetry (LoS) shown below using a dashed line.
Any shape that can be folded down a line to get two matching halves is said to have a line symmetry. The number of lines of symmetry for a shape can be determined by using a ruler to visualize when the shape or object can be divided equally into 2 equal pieces that are a reflection of each other.
A line of symmetry is an imaginary line that divides a shape into two equal halves, in a way that each half is a mirror image of the other. When a shape is folded along its line of symmetry, the two halves match exactly.
This Maths article shows how to find lines of symmetry on shapes and practise drawing them.
A figure has line symmetry if it can be reflected across a line back onto itself. An isosceles triangle has one line of symmetry from its vertex to the midpoint of the base. The letter W has one line of symmetry through its middle.
