it can be in any shape with even number of sides.
An equilateral shape would have equal and opposite sides.
Rectangle
A parallelogram is a four sided shape where opposite sides are parallel and equal lengths. If you mean that ALL sides are equal lengths, you are looking for a rhombus.
This just means that opposite sides in a shape (sides that 'look' at each other) are of equal lengths.
an perticulogram
A shape that has two pairs of opposite sides that are equal is a parallelogram. This includes specific types of parallelograms such as rectangles and rhombuses, where the opposite sides are not only equal in length but also have specific angles or properties. In general, all parallelograms have this characteristic property of equal opposite sides.
square + rectangle
circle
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 square has 4 equal sides with opposite angles that are equal.
The shape described is a parallelogram, specifically a rhombus. In a rhombus, opposite sides are equal in length, and opposite angles are equal. Additionally, none of its angles are 90 degrees, which differentiates it from rectangles and squares.
