this is what's called a rhombus. it is essentially a tilted square (meaning that the four sides still have the same length, even though the area changes.) If it had right angles it would be a square.
what's interesting is that you didn't need to even state that it has parallel sides. A quadrilateral automatically has 2 pairs of parallel sides if all the sides are equal.But it can also be a parallelogram
rhombus

A rectangle
A parallelogram. Opposite sides are parallel and congruent.parallelogram is a quadrilateral with two sets of parallel sides. The opposite sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are congruent. The three-dimensional counterpart of a parallelogram is a parallelepiped.Parallelogram - A quadrilateral whose opposite sides are parallel
A parallelogram has opposite sides and angles congruent which means of equal measure.
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.
The quadrilateral described is a rectangle. In a rectangle, opposite sides are equal and parallel, and all four angles are right angles. This definition meets the criteria of having one pair of opposite sides that are equal and parallel, along with the presence of right angles.
rhombus
quadrilateral
rhombus. The rhombus is a quadrilateral with all sides equal in length. It is also a parallelogram, so opposite sides are parallel and equal in length, and opposite angles are equal.
A square or maybe a rectangle as well would fit the given description
A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal
All quadrilaterals apart from rectangles. Even parallelograms have adjacent angles that are not equal.
Yes, the opposite angles in a regular quadrilateral are equal.
A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length, and opposite angles that are equal. Two ways to describe a parallelogram could be as a shape with opposite sides that are both parallel and equal in length, or as a shape with opposite angles that are equal.
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
