No a parallelogram cant be concave because the only parrallelograms there are arent concaveParallelograms...*rectangle *square* rhombus*rhomboidMeaning of concave-polygons that have parts that go into the shape.
A bigger square, a rectangle, an irregular concave hexagon, an irregular concave octagon are all possibilities.
it doesnt have a name if it has the name is square
A square is one example but there are many other (concave) shapes.
A square. Or an irregular, concave shape with with 5 or more sides.
A regular polygon has all its angles of equal measure, and its sides of equal length. In the case of a quadrilateral, that would mean a square. A concave quadrilateral must have at least one reflex angle and so cannot be a square. So it cannot be regular.
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
Concave, because you can connect the corners from the outside.
Concave is a property of [irregular] polygons. A parallelogram cannot be concave.
