Rotational symmetry means it will look the same after being rotated a certain amount.
Let's assume that you mean a regular octagon where the sides are all equal in length and the angles are all the same (135 degrees).
With such an octagon, if you rotate it one turn to the right (that's 45 degrees), it will look just the same. Rotate another 45° and it is still the same. You can do this 8 times so we say that a regular octagon has an order of rotational symmetry of 8.
It need not have any rotational symmetry (ie order 1). Or, it can have symmetries of order 2, 4 or 8.
An octagon has eight-fold rotational symmetry, because rotation of octagon by 45 degrees (one-eighth of a full circle) produces a figure that is superimposible on (or congruent to) the original.
It has rotational symmetry to the order of 2
A regular nonagon with 9 sides has a rotational symmetry of 9.
Yes, a crescent has a rotational symmetry.
A regular octagon has 8 lines of symmetry.
If it is a regular octagon then it has rotational symmetry to the order of 8
If it's a regular 8 sided octagon then it rotational symmetry to the order of 8
It has 8lines of rotational symmetry
If it is a regular octagon then it has rotational symmetry to the order of 8
yes
A sphere has rotational symmetry of an infinite degree.
It has 8 rotational symmetry.
I believe that an octagon has 16 lines of symmetry.
An octagon has eight-fold rotational symmetry, because rotation of octagon by 45 degrees (one-eighth of a full circle) produces a figure that is superimposible on (or congruent to) the original.
bilateral and rotational symetry
8
Of course it can!!! ;) 8 lots (lines of symetry which r rotational)
