A parallelogram has a rotational symmetry of 2!
In a regular octagon, each angle is 135 degrees. If the octagon is not regular, then it can have as many as 6 right angles in it.
8 sides. octagon is referring to the number eight.
8
An octagon has 8 sides and a quadrilateral has 4 sides.An octagon has 8 - 4 = 4 more sides than a quadrilateral.
It has 8 rotational symmetry.
I believe that an octagon has 16 lines of symmetry.
There are no right angles in an octagon.An 8 sided octagon normally has no right angles.
Infinitely many.
An ellipse has rotational symmetry of order 2.

Two.
A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflective symmetries (six lines of symmetry).
If it's a regular 8 sided octagon then it rotational symmetry to the order of 8
