This is a parallelogram if it has 4 sides
rhombus
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.
Depends how it's cut
Any shape with at least two straight sides can have opposite parallel and congruent sides. For example, a running track.
rectangle
every parallelogram
Parallelogram, Rectangle, and Isosceles Trapezoid, opposite sides are congruent.
A kite
its a shape
A polygon with 2n sides (n>1) can have opposite angles congruent.
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.
This quadrilateral is a trapezoid. In a trapezoid, one pair of opposite sides is parallel, and one pair of opposite sides is congruent. The other two sides are not parallel or 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.
