If it's 3D then it could be a rectangular pyramid.
A kite, a rhombus, a square must have two pairs of adjacent sides that are equal. Irregular polygon with 5 or more sides can have two pairs of equal sides.
A rectangle
A rectangle is defined as any shape with two pairs of equal sides and four equal angles.
a quadrilateral
It has two pairs of equal length (congruent) sides. The top two are equal and the bottom two are equal (when you draw it like a diamond shape)
If it has four equal sides, then two parallel sides implies two PAIRS of parallel sides. The shape is a rhombus.
A shape that has two pairs of adjacent sides that are equal is a rectangle. In a rectangle, opposite sides are equal in length, and the adjacent sides also have equal lengths due to the right angles formed at each corner. Additionally, a rhombus is another example, where all four sides are equal, and consequently, it has two pairs of adjacent sides that are equal.
A kite or arrowhead.
A parallelogram or kite.
A kite.
The shape you are describing is a rhombus. A rhombus has two pairs of parallel sides, and all four sides are of equal length. Additionally, opposite angles are equal, and the diagonals bisect each other at right angles.
A Kite : This is a quadrilateral having two pairs of adjacent sides equal in length.
