A trapezoid - see related link for an example.
A pentagon maybe even A polygon
If both pairs of opposite sides are the same length, and both pairs of opposite angles are the same, the quadrilateral is a parallelogram (rhombus, rectangle, or square).
Opposite sides are of equal length and parallel. The four angles are all right-angles (90 degrees( .
The length of the rhombus is equal to the length of the diagonal formed by the bisector of the 2 opposite acute angles.
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 parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.
No, there is no country called Rhombus. Rhombus is actually a geometric shape with four sides of equal length and opposite angles of equal measure.
Rhombus!
square
Yes, the base angles of an isosceles triangle are always congruent. An isosceles triangle commonly has two sides that are equal in length. The base angles are the angles opposite those two equal sides of the triangle. A geometric theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent. The converse is also true.

If both pairs of opposite sides are the same length, and both pairs of opposite angles are the same, the quadrilateral is a parallelogram (rhombus, rectangle, or square).
A rectangle. As long as the sides that are opposite of each other are the same length(required to get the 90 degree angles) but both sets must be different lengths or else you get a square
Opposite sides are of equal length and parallel. The four angles are all right-angles (90 degrees( .
The length of the rhombus is equal to the length of the diagonal formed by the bisector of the 2 opposite acute angles.
