There are no right angles in an octagon.
An 8 sided octagon normally has no right angles.
The angle of all corners in an octagon is 135 degrees. All angles together are 1080 degrees.

An object with rotational symmetry looks the same after a certain amount of rotation. A regular octagon does have rotational symmetry.
Seven lines of symmetry.
it has 7
It has 8 rotational symmetry.
9 reflection
5
18
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
Infinitely many.
An ellipse has rotational symmetry of order 2.
2
Two.
A regular hexagon has rotational symmetry of 6. Usually we can figure out the rotational symmetry of most shapes by looking at how many sides they have. Such as an octagon has rotational symmetry of 8 ect. Hope it helped!
