There are many shapes: Any regular polygon.
An irregular polygon with an even number of sides in which the opposite sides and angles are equal.
An irregular polygon with 3n sides where every third side is equal and every third angle is equal.
and so on.
A circle, ellipse, disc, oval
A rectangle
Oh, what a lovely question! A crescent shape does indeed have rotational symmetry. If you were to turn it around its center point, it would look the same at certain angles. Isn't that just a happy little discovery?
Triangle * * * * * The only triangle with rotational symmetry of order 3 is an equilateral triangle and that has 3 lines of symmetry, not 0. The triskelion (the three legs) on the Isle of Man flag has rotational symmetry of order 3 but no lines 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.
It has rotational symmetry to the order of 2
Yes. Any equilateral shape can have both rotational and line symmetry.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
none shapes have 1 rotational symmetry because in rotational symmetry one is none
A semicircle.
circle
A line segment would have rotational symmetry.
Rotational symmetry is the amount of symmetry you would have if you rotated the shape.
No.
If it is a regular 5 sided pentagon then its order of rotational symmetry is 5
A rhombus is one example.
A square
A rectangle
