Does a hexagon have rotational symmetry?
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.
Does kite have rotational symmetry?
Answer No. If the shape has rotational symmetry, then it should be able to match itself when rotated a certain number of degrees that IS NOT 360 degrees. Why? Well, if we stop and think about it, all shapes can match themselves when being rotated 360 degrees (a full circle.) If 360 degrees was valid and qualified for rotational symmetry, then any shape would have rotational symmetry. Then this classification of rotational symmetry would have no real conclusion. The only way a kite can match itself when rotating is if you rotate it 360 degrees. Therefore, it does not have rotational symmetry.
Which shape has line of symmetry but not rotational symmetry?
There are infinitely many such shapes:Take any odd-sided regular polygonMove one vertex away from the side opposite it in a perpendicular direction any distance you like.The resulting shape has one line of symmetry (from the vertex moved to the centre of the opposite side) and no rotational symmetry.Done to an equilateral triangle (a regular "3-agon") this creates an isosceles triangle.
What is a rotation of symmetry?
Sometimes called rotation symmetry, or symmetry of rotation. If you have an object that can be turned through a certain angle (like rotating a cube through 90o) and then it looks identical, then that object has a certain symmetry under rotation. If you can turn it through any angle, like a cylinder, then it has rotation (or rotational) symmetry.
When an image has a point of symmetry then any line containing that point will be a line of symmetry?
False
Can a shape have rotational symmetry and line symmetry?
Yes. Any equilateral shape can have both rotational and line symmetry.
Does the shape a crescent moon have any rotational symmetry?
Yes
Does a hexagon have rotational symmetry?
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.
What shape has twofold rotational symmetry?
Any shape which, when rotated through 180 degrees appears to be the same as the original.
Does an isosceles triangle have any rotational symmetry?
An isoceles triangle does not have rotational symmetry.
Does kite have rotational symmetry?

The only way a kite can match itself when rotating is if you rotate it 360 degrees. Therefore, it does not have rotational symmetry.
How many order of rotational symmetry does a irregular pentagon have?
They have not got any rotational symmetry
Does an equilateral triangle have any rotational symmetry?
An equilateral triangle has rotational symmetry (order 3).
Does a square have any turns rotational symmetry?
Yes. A square has rotational symmetry of order 4.
Does a decagon have rotational symmetry?
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.
What figure has symmetry if there is a rotation of 180 degrees or less that maps the figure onto itself?
Any shape with a rotational symmetry of order 2 or more.
What type of figure is rotational symmetry?
Rotational symmetry is when you turn or rotate a shape and it still looks the same. A circle is the most common answer. However, it you rotate a square about 90 degrees, it still looks the same, so it is considered rotational symmetry. Technically, any shape can have rotational symmetry because it you rotate it 360 degrees, it still looks the same.Definition of rotational symmetry:Generally speaking, an object with rotational symmetry is an object that looks the same after a certain amount of rotation. An object may have more than one rotational symmetry; for instance, if reflections or turning it over are not counted. The degree of rotational symmetry is how many degrees the shape has to be turned to look the same on a different side or vertex. It can not be the same side or vertex.
