What is a rectangle in geometry with diagram - find out its definition and properties with calculation of diagonal, area and perimeter using formulas
A quadrilateral having opposite sides equal and each angles 90° (right angle) is called a rectangle. Or, we can say, a rectangle is a parallelogram with each angle 90°. So, each rectangles are parallelograms but each parallelograms are not rectangles.
