It is an 8 sided polygon - a plane shape bounded by 8 straight lines of equal length. The angles need not be of the same measure.
No, there is no need for it to be equilateral.
Not necessarily. A rhombus is an equilateral quadrilateral but does not have a line of symmetry. An irregular octagon does not, either.
No, they cannot.
an octagon * * * * * An octagon need not have equal sides. For that it would have to be an equilateral octagon (though not necessarily regular).
No but they will make a hexagon

Oh, dude, an octagon has 8 sides, right? So, if you draw all the diagonals from one vertex, you'll get 4 equilateral triangles. But, like, if you count all the equilateral triangles in the octagon, there are actually 20 of them. Math can be pretty wild, huh?

Octagonal An octagon has eight sides and eight angles, and is a two-dimensional shape. In an equilateral octagon, each side has a degree measure of 135.
yes
An equilateral triangle, a square, a rectangle, an octagon.
Only if all the SIDES are EQUAL in length. Equi -> Equal Lateral -> Sides To actually answer the question: An octagon has all sides the same length and its internal angles are all the same size. All regular polygons except for a triangles are equilateral.
