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.
This is a parallelogram if it has 4 sides
rhombus
A square's opposite sides are parallel and all the sides are congruent.
Yes opposite sides are parallel and congruent
rectangle
every parallelogram
its a shape

The Opposite Sides Parallel and Congruent Theorem states that if a quadrilateral has a pair of opposite sides that are parallel and congruent, then the quadrilateral is a parallelogram.
No. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. The opposite angles not congruent.
A rhombus (4 congruent sides, diagonals perpendicular)that is not also a square (no right angles), andis also a parallelogram (opposite sides parallel and congruent, opposite angles congruent). It is also a quadrilateral, which has 4 sides.
A square's opposite sides are parallel and all the sides are congruent.
Yes opposite sides are parallel and congruent
