Symmetry in 2D Shapes
Symmetry is show when you can draw a line through a shape and the
shapes created on either side of the line would be exactly the same but
reflected (flipped over). This line would be called a line of symmetry.
A shape can have one line of symmetry, several lines of symmetry or no
lines of symmetry whatsoever.
Let’s see if we can find lines of symmetry in some common 2D shapes.
Regular polygons will have the number of lines of symmetry as they have
sides. A square will have 4 lines of symmetry, a pentagon will have 5, and
a hexagon will have 6 and so on.
