Yes. A square has rotational symmetry of order 4.
An isoceles triangle does not have rotational symmetry.
Yes. Any equilateral shape can have both rotational and line symmetry.
An equilateral triangle has rotational symmetry (order 3).
No.
The letter "Z" has two lines of rotational symmetry. When rotated 180 degrees, it looks the same, but it does not have any other angles at which it maintains its appearance. Thus, it exhibits rotational symmetry only at this specific angle.
A square, hexagon
An isoceles triangle does not have rotational symmetry.
They have not got any rotational symmetry
Yes. Any equilateral shape can have both rotational and line symmetry.
An equilateral triangle has rotational symmetry (order 3).
Yes. Any even sided figure will have a rotational symmetry. Yes. If it is a regular shape such as a square, hexagon or octagon (equilateral and equiangular) then the rotational symmetry is the same as the number of sides. Rotational symmetry is basically if the shape is rotated, is it exactly the same as it was before. A hexagon can be rotated 6 times and still be the same without actually being in the the same postition, so a hexagon has a rotational symmetry of 6.
heck yeah it does * * * * * It can do, but it need not have any non-trivial rotational symmetry. A regular decagon will have rotational symmetry of order 10.
No.
It need not have any symmetry.
no they don't
I think none. In fact the only triangle that I believe has any rotational symmetry is an equilateral triangle.
It need not have any rotational symmetry or it can have 5.
