A polygon; specifically a tetragon. A two-dimensional shape with four equal sides and four right angles is a square. A two-dimensional shape with two sets of equal sides and four right angles is a rectangle. A two-dimensional shape with two sets of equal sides and two sets of equal angles is a parallelogram. A parallelogram where each opposite angel bisects the shape is a rhombus. A two-dimensional shape with one set of equal, parallel sides and two sets of equal angles is a trapezoid. A three-dimensional shape with four triangular faces is a tetrahedron.
a pollygon
A general trapezium, and selected versions of polygons with 5 or more sides.
It has one pair of opposite angles that are equal but not two.
It is a trapezoid that can have two right angles plus one obtuse angle plus one acute angle and the four angles add up to 360 degrees.

If a set of equal sides are adjacent, then the quadrilateral is a "kite" shape. If a set of equal sides are opposite, then the quadrilateral is a parallelogram.
It can't. Squares have right angles and 4 equal sides. A rhombus has 4 equal sides and the opposite angles must be equal, but they do not have to be 90 degrees. Squares are a special case of rhombi, or a sub-set of them if you like.
A rectangle or a square are sets of quadrilaterals with two pairs of right angles. They each have two pairs of right angles and two sets of equal sides.
An irregular pentagon such as a child's silhouette of a house: a rectangle shape (open at the top) forming the body of the house, with a triangular roof on of the rectangle. The vertical line through the apex of the roof is the line of symmetry. The two walls, and the two roof lines are the two sets of equal sides. The two right angles at the base are the one set of matching angles.
A trapezium and a square are both quadrilaterals, but the key difference is the number of parallel sides. A square has two sets of parallel sides and four right angles, while a trapezium has only one set of parallel sides. Parallel sides: A square has two pairs of parallel sides, while a trapezium has only one. Angles: A square has four right angles, while a trapezium can have any combination of angles as long as the interior angles add up to 360°. Side lengths: A square has four equal sides, while a trapezium can have sides of different lengths. Classification: A square is a regular quadrilateral because all its sides and angles are equal. A trapezium is not a parallelogram because only one pair of sides are parallel.
It has four sides of equal length and the corner angles are all equal.

A two-dimensional shape with two sets of equal sides and four right angles is a rectangle. A two-dimensional shape with two sets of equal sides and two sets of equal angles is a parallelogram. A parallelogram where each opposite angel bisects the shape is a rhombus. A two-dimensional shape with one set of equal, parallel sides and two sets of equal angles is a trapezoid. A three-dimensional shape with four triangular faces is a tetrahedron.
A polygon with 4 or more sides can meet these requirements.
trapzoid
If one set of opposite sides is equal and parallel then both are. The figure is a PARALLELOGRAM and the opposite angles of course must be equal.(see related links below)Parallelograms include rectangles (four right angles) and rhomboids (two opposite acute angles and two opposite obtuse angles).A square is a type of rectangle (all sides equal).A rhombus is a type of rhomboid (all sides equal).Although a square could be considered an equiangular rhombus, it is usually considered a separate type of shape.
