That's a rhombus. With an additional constraint on the angles, it's also a square.
A paralleogram has no meaning. However, a parallelogram is a four sided plane (2-dimensional) figure which has two pairs of [opposite] sides that are parallel.
nothing fits the definition of rhombus and rectangles becauses the definition for rectangle is : a plane figure with four straight sides and FOUR RIGHT ANGLESbut the definition of rhombus is...a parallelogram with ,OPPOSITE EQUAL ACUTE ANGLES and OPPOSITE EQUAL OBTUSE ANGLES, and four equal sides.
Parallel.
A parallelogram is a plane figure with four straight sides such that the two pairs of sides opposite to one another are also parallel to one another. The bit below, added by another contributor, is about parallel lines and that is not the same thing! * * * * * A parallelogram is two lines that don't intersect
A trapezium (as it is known in English) is a quadrilateral which is a closed plane figure with four straight sides. It has one pair of parallel sides. The other pair of sides is not parallel (otherwise the figure would become a parallelogram).
A quadrilateral (ie 4-sided plane figure) with opposite sides equal and parallel
If both sets of opposite sides are parallel and not equal, the shape cannot be a plane figure. It must be a projection of a parallelogram onto a spherical surface (or similar).
A rectangle (opposite sides are parallel which is a parallelogram!)
A parallelogram is a four-sided plane figure with opposite sides parallel.
A rhombus or a parallelogram
Yes, it can... but does not have to. A parallelogram is a four-sided plane figure with opposite sides parallel. So as long as it has opposite sides that are parallel, it is a parallelogram.
Square. Square is a quadrilateral and all sides are equal and opposite sides are parallel, the sum of the interior angle measure 3600.
A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel. Hope this helps!
square or rhombus
Every rectangle is a parallelogram. The description of a parallelogram is: -- a figure that lies in a single plane -- it has four sides -- opposite sides are parallel -- opposite sides have equal lengths -- alternate angles are equal Every rectangle satisfies this description.
Yes. A quadrilateral is any plane figure bounded by four straight lines. A rectangle is a quadrilateral with each of its vertex angles equal to 90°, opposite sides are parallel and of equal length but the pairs of opposite sides are of different lengths. A square is a rectangle with all its sides equal in length.
It is not possible for a quadrilateral in Euclidean plane geometry to have no equal angles and still have its opposite sides parallel.It's possible for a quadrilateral to have no equal angles and two of its sides parallel (opposite ones, obviously; adjacent sides can't possibly be parallel). That would be a trapezoid.
