No. It is the opposite sides of a regular octagon that are parallel and congruent.
An octagon has four (4) diagonals, each connecting two opposite vertices.
There are 8 lines of symmetry. Those that bisect opposite sides and opposite vertexes.
A regular octagon's angles and sides are all the same. As in the angles are the same, and the lengths of each side are the same. And irregular is basically the opposite of that.
Half an octagon has five sides is it is divided in two by a line joining opposite vertices. It has six sides in the dividing line joins the midpoints of opposite sides.
Yes:As the shape is regular all sides are equal in length (and congruent).An octagon has 8 sides. As this is an even number of sides, the opposite sides are parallel.
8. 4 between the opposite vertices 4 between the mid points of opposite sides.
If the "8 by 8 octagon" refers to the distances between its opposite sides rather than opposite vertices (its principal diagonals), then the side lengths are 8*[sqrt(2) - 1] units of length.
An octagon is neither a quadrilateral nor a parallelogram. "Quadrilateral" refers to a shape that has four sides. "Parallelogram" refers to a shape that has two pairs of opposite, congruent sides. An octagon has eight sides, and since eight is not equal to four, an octagon is neither a quadrilateral nor a parallelogram.
I am a square or a rectangle or maybe even a hexagon, octagon, or decagon...
Any even-sided, regular shape will have opposite sides parallel. A square, hexagon, octagon and decagon are just four examples !
