Quadrilaterals are Parallelograms, Rhombuses, Rectangles and Squares

Quadrilaterals

The quadrilaterals family tree includes parallelograms which further entail rhombuses, rectangles and squares. Moreover, another name of quadrilateral is quadrangle. If the quadrangle two pairs of opposite sides are parallel then it is called a parallelogram. Every two adjacent angles give the sum of the straight angle, opposite angles are the same, as well as the lengths of the opposite sides. In addition ti this, diagonals in a parallelogram bisect each other, which is due to the fact that the parallelogram has a centrally symmetric body under the intersection of the diagonals. General parallelogram is also called rhomboid. According to the lengths of sides are equilateral parallelograms, which have all the same length. Equilateral parallelograms are in addition to the perpendicular diagonals, and they are actually a special case of deltoid, are also tangential. Such parallelogram that has no intrinsic right angles is called rhombus (Leech, 2006).

According to the size of the internal angles parallelograms are also divided into rectangular parallelograms whose interior angles are all the same size, a right and oblique. Rectangular parallelograms are cyclic which are generally known as the rectangles (Griffin, Witonsky and Willmore, 2008). In addition to this, the parallelogram, which is rectangular, while equilateral are called a square, which is defined as regular quadrilateral. The properties of quadrilaterals include the following:

The word quadrilateral is derived from “quad” which means 4 and “lateral” means “sides”.

A quadrilateral is a polygon with four corners and four sides.

The interior angles sizes of quadrilateral add to 360 degrees.

Quadrilaterals with two sets of parallel side are known as the parallelograms.

Any quadrilateral with four equal sides of length and four right angles is known as the square. In addition to this, the area of a square is equivalent to ...
