Question

what is definaton of rhombus​

Answer 1

Answer:

Step-by-step explanation:

A rhombus is a parallelogram with all sides equal in length. ... The word rhombus comes from the Greek word rhombos, meaning "spinning top". A rhombus is sometimes called a diamond, but not all rhombi are diamond shaped. To find the perimeter of a rhombus, just add up all the sides.

Answer 2

Answer:

Rhombus is a special type of a parallelogram whose all sides are equal.

The difference between a square and rhombus is that all angles of a square are right angles, but the angles of a rhombus need not be right angles. 

So, a rhombus with right angles becomes a square.

We can say, “Every square is rhombus but all rhombus are not square.”

 

Properties of a rhombus

The given table describes the properties of a rhombus.

 All sides of a rhombus are equal.

 Here, AB = BC = CD = DA.

 Diagonals bisect each other at 90°

 Here, diagonals AC and BD bisect each other at 90°

 Opposite sides are parallel in a rhombus.

 Opposite angles are equal in a rhombus.

 Here, AB ∥ CD and AD ∥ BC.

 ∟A = ∟C and ∟B = ∟D.

 Adjacent angles add up to 180°.

 ∠A + ∠B = 180°

 ∠B + ∠C = 180°

 ∠C + ∠D = 180°

 ∠A + ∠D = 180°

Real-life examples

Rhombus can be found in a variety of things around us, such as a kite, windows of a car, rhombus-shaped earring, the structure of a building, mirrors, and even a section of the baseball field.
