a shape with a line of symmetry
A symmetrical shape is said to have line symmetry. A shape that has line symmetry can have one or more lines of symmetry
Septahedron
There are 11 letters with only one line of symmetry.
A shape does NOT need to have line symmetry in order to have rotational symmetry.For example, the letters N, Z and S can be rotated 180° to show symmetry, but none of these show line symmetry.When the folded part Line of Symmetry. Here I have folded a rectangle one way, and it didn't work.
The 2D shape which has one line of symmetry is the trapezium.
C has 1 horizontal line of symmetry V & W have one vertical line of symmetry.
An isosceles triangle has one line of symmetry
An isosceles triangle has one line of symmetry
