No
octogan
i think about 110 degrees
Since it is not a regular octagon, any value that you like.
That is a regular octogan (8 sided shape)
An irregular octogan?
no an octogan has eight sides while a hexagon only has six sides
a right angle is a right angle
Because a right angle is a right angle.
A right angle is an angle of 90 degrees.
A regular octogan has 8 lines of symetry, and a irregular octogan has 2 lines of symetry.
I have no idea about an octogan. An octagon can have none, one, two, up to 8 lines of symmetry.
A right angle is a angle with 90o
