Learn and know what is the **definition of rectangle**? in an easy way in geometry. Actually when we are studying quadrilaterals, we get rectangle topic.

In quadrilaterals, we will study types of quadrilaterals; in that rectangle is one of them. Now we are going to study what is a rectangle? (definition of rectangle), then we will know the shape of a rectangle that means we will see how the rectangle looks like generally, then finally we will see some real life examples of rectangle.

**Definition of rectangle as follows:**

If we want to give the **definition of rectangle** we can give like this “a quadrilateral in which opposite sides are equal and parallel and the four angles are 90^{0}, consecutive sides are not equal is called a rectangle”.

Second definition of rectangle is “if one of the angle of a parallelogram is equal to 90^{0} is called as rectangle”.

**Third definition of rectangle** is “a square is called as a rectangle if adjacent sides are different in length and opposite sides are equal”.

The above are the three **definitions for a rectangle** we can give.

**Shape of rectangle:**

The shape of rectangle looks like this, observe the below diagram, I have shown the rectangle picture.

**Some important words used related to rectangle:**

Length: in the above diagram, the line segment AB and CD we call as length of rectangle.

Breadth: in the above diagram, AD and BC we call as breadth of rectangle.

Diagonal: in the diagram, AC and BD are called as diagonals of the rectangle.

**Some basic properties of rectangle:**

The opposite sides i.e. AB and CD, AD and BC are equal.

All the angles will be equal to 90^{0}.

The two diagonals i.e. AC and BD are equal.

The diagonal of a rectangle will divide the rectangle as 2 congruent right angled triangles.

Hope now you have understood the **rectangle definition** and the some important points of rectangle.
