Parallelogram, square, diamond, rectangle calculator

In planar geometry, a square is a polygon with four equal sides and four equal interior angles combined. A square is a type of regular polygon, also called a regular quadrilateral. Each internal angle is a right angle, which is 90 degrees.

In geometry, a rectangle (also known as a rectangle Rectangle) is defined as four quadrilaterals with equal internal angles, that is, all interior angles are right angles. From this definition, it can be concluded that the two opposite sides of the rectangle are equal in length, that is, the rectangle is a parallelogram. A square is a special case of a rectangle whose four sides are of equal length. At the same time, the square is both rectangular and diamond shaped.

In a plane, a set of parallelograms with equal sides are rhombic.

There are two sets of quadrilaterals with equal diagonals in the same plane called parallelograms.
