 # 8th Class Chapter No 3 - Understanding Quadilaterals in Maths for CBSE NCERT

## Parallelogram

A parallelogram is a two-dimensional geometrical shape, whose sides are corresponding with one another. It is comprised of four sides, where the pair of equal sides are equivalent long. Likewise, the contrary points of a parallelogram are equivalent to one another. The territory of parallelogram relies upon the base and stature of it.
In geometry, you probably found out about numerous 2D shapes and sizes, for example, circle, square, square shape, rhombus, and so forth. These shapes have an alternate arrangement of properties. Additionally, the zone and border recipes of these shapes shift with one another, used to take care of numerous issues. Let us learn here the definition, recipes and properties of a parallelogram.

Properties: Opposite sides are equivalent.
Inverse edges are equivalent.
Diagonals cut up each other

## Rhombus

In Euclidean geometry, a rhombus is a sort of quadrilateral. It is an extraordinary instance of a parallelogram, whose diagonals crosses each other at 90 degrees. This is the essential property of rhombus. The state of a rhombus is in a precious stone shape, thus it is additionally called a jewel. You more likely than not seen the precious stone shape in the playing a game of cards. All the rhombi are parallelogram and kite. What's more, in the event that the edges of the rhombus are every one of the 90 degrees, at that point it is a square.

Properties: All the properties of a parallelogram.
Diagonals are opposite to one another

## Square shape

A Rectangle is a four sided-quadrilateral having all the inward points to be correct calculated (90o).
It is to be noticed that in a square shape the contrary sides are equivalent long which makes it unique in relation to a square.
For instance, in the event that one side of a square shape is 20 cm, at that point the side inverse to it is additionally 20 cm.
A square shape is portrayed by length (L) and width (W). Both length and width are distinctive in size.
In the figure over, a square shape ABCD has four sides as AB, BC, CD, and DA and right edges A, B, C, and D. The separation among An and B or C and D is characterized as the length (L), while the separation among B and C or An and D is characterized as Width (W) of the given square shape.

## Properties:

All the properties of a parallelogram.

Every one of the edges is a correct edge.
Diagonals are equivalent.

## Square

In Geometry, a square is a two-dimensional plane figure with four equivalent sides and equivalent points. In this article, we will talk about the meaning of the square, properties of square and the terms identified with a square and the connection between them.

## Properties:

All the properties of a parallelogram, rhombus and a square shape.

## Zone of a Kite Formula

A quadrilateral is a polygon which has 4 vertices and 4 sides encasing 4 edges. Kite is an exceptional quadrilateral where each pair of the back to back sides is consistent, however the contrary sides are not compatible. Rhombus is a kite with all the four sides compatible.

## Properties:

The diagonals are opposite to each other
One of the diagonals cuts up the other.
