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
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.
A parallelogram has rotational symmetry. A parallelogram does not have reflectional symmetry. The easiest way to do this is to draw a point in the middle of the shape and rotate it to see if the point looks the same from all angles.
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 line segment would have rotational symmetry.
Rotational symmetry is the amount of symmetry you would have if you rotated the shape.
If it is a regular 5 sided pentagon then its order of rotational symmetry is 5
A tetrad has rotational symmetry of order 4. It also has no lines of symmetry. It is also known as a swastica.
A rhombus is one example.
