Here are 10 Properties of a Rhombus A Rhombus is a Quadrilateral A Rhombus has four sides. Moreover, all the sides of a rhombus are equal in length, and the diagonals bisect each other at right angles. The diagonals are perpendicular bisectors of each other. In geometry, a quadrilateral can be defined as a closed, 2-D shape that has four straight sides.It is a kind of polygon which has four vertices or corners. The diagonals bisect the angles. Rhombus is a special type of a parallelogram whose all sides are equal. Opposite interior angles of a rhombus are congruent. No matter how you arrange those four linear objects on your flat surface, you will always have two pairs of equal opposite angles. If you have a rhombus with four equal interior angles, you have a square. Also, opposite angles of a rhombus are equal, which means summing up the four angles will give you 360°, i.e. (defdate from 16th c.) ¹. The quadrilateral is basically of 6 types such as: A rhombus is a special case of a parallelogram, and it is a four-sided quadrilateral. Look at the bottom left angle and the top right angle. Therefore, the area of rhombus = 36 square units. Properties of Quadrilaterals. Definition. Since the opposite sides of a rhombus have the same length, it is also a parallelogram. You will get a rectangle, where the midpoints of the 4 sides are joined together, and the length and width of the rectangle will be half the value of the main diagonal so that the area of the rectangle will be half of the rhombus. In Euclidean geometry, a rhombus is a special type of quadrilateral that appears as a parallelogram whose diagonals intersect each other at right angles, i.e., 90 degrees. Squares. In a rhombus, opposite sides are parallel and the opposite angles are equal. And if a rhomboid has all sides equal, it becomes a rhombus.
