No a parallelogram cant be concave because the only parrallelograms there are arent concave
Parallelograms...*rectangle*square
* rhombus
*rhomboid
Meaning of concave-polygons that have parts that go into the shape.
yes a parallelogram is a parallelogram
A nonconvex polygon is a concave polygon. All polygons with 4 or more sides can be concave. An arrowhead is an example of a concave quadrilateral. The back of an envelop (where the sides are folded and glued together) is a concave pentagon.
because both lines are paralle so it is a parallelogram
A concave hexagon or a concave octagon.
A square is always a parallelogram. Every square is a parallelogram.
Concave is a property of [irregular] polygons. A parallelogram cannot be concave.
A rhombus is an equilateral parallelogram. As such, it is neither concave nor convex.
A rhombus is an equilateral parallelogram. As such, it is neither concave nor convex.
The answer depends on the shapes. Some possible answers are: parallelogram, trapezium, pentagon, heptagon (concave).The answer depends on the shapes.

A kite or, if concave, an arrowhead or chevron.
The remaining shape could be a [concave] hexagon although in some circumstances it could be a smaller parallelogram.
Rectangle, rhombus, parallelogram, trapezium, kite. Also a chevron, which is a concave 4-sided shape.
It depends entirely on their relative shapes and sizes. They could make a triangle, a parallelogram, a square, or a pentagon or even a concave heptagon.
Assuming they don't overlap, these are some of the possible shapes: a concave pentagon, a trapezium, a concave seven or eight sided figure (neither of the last two is a polygon but two polygons touching one another).
concave
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
Depending on how they are joined, you can get a square, rectangle, rhombus, parallelogram, kite, arrowhead (or delta). You could also get a concave pentagon or hexagon.
