a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
Any two opposite sides of a parallelogram are called bases, a distance between them is called a height. If all angles of parallelogram are 90 degree then it can either be a rectangle or a square. ... Only opposite sides of a rectangle are equal unlike square which has all .
The opposite internal angles of both a parallelogram and rectangle are equivalent. The main difference is that a rectangle always has angles of 90°, while that of a parallelogram may vary. In other words, the angles of a rectangle are always equal, or equiangular.
The basic difference between rhombus and parallelogram lies in their properties, all the sides of a rhombus have the same length, whereas parallelogram is a rectilinear figure whose opposite sides are parallel.
