An IRREGULAR octogon
A regular octagon has eight equal sides, but in general the sides of an octagon don't have to be equal as long as there are eight of them.

a octagon hexagon
A regular octagon has 8 sides similarly to an octagon. The name regular octagon means that all angles are the same, therefore inferring that all sides are of equal length.

It has 8 equal sides.
No, it is not necessary. Only a regular octagon needs to have equal sides and angles.
basicly regular octagon No, it's a hexagon. An octagon has 8 equal sides and 8 equal angles.
Only if it's a regular octagon.
An octagon has to equal 8 sides. Oct- means 8. So 8 sides.
An octagon
Both, in a way. An octagon gets its name from the word meaning, "eight angles" so an octagon can have eight unequal sides. However, a regular octagon is a closed eight-sided figure with sides of the same length and internal angles of the same size.
