Rotational symmetry of order 1.
They have not got any rotational symmetry
The rectangle's rotational symmetry is of order 2. A square's rotational symmetry is of order 4; the triangle has a symmetry of order 3. Rotational symmetry is the number of times a figure can be rotated and still look the same as the original figure.
A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflective symmetries (six lines of symmetry).
A line has 180 degrees rotational symmetry.
None.
i am not sure but i think a trapezium has 1 order of rotational symmetry
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
infinite angles of rotational symmetry... (: ~kitty <3 = =
A line has rotational symmetry of order 2.
Rotational symmetry of order 1.
It has 1 order of rotational symmetry.
A general parallelogram has rotational symmetry of order two.
They have not got any rotational symmetry
If it's a regular 8 sided octagon then it rotational symmetry to the order of 8
All of them. To be precise, since a circle is perfectly round (in theory, although humans can't reproduce such circularity - is that a word?) it will have infinity rotational symmetry.
A scalene triangle has one order of rotational symmetry.
