Quadrilaterals:


Quadrilaterals:

A Quadrilaterals is a polygon with four sides (or 'edges') and four Vertices or Corners,its basically a figure formed by joining four points in an order is called a quadrilateral.Look around you and you will find so many objects which are of the shape of a
quadrilateral - the floor, walls, ceiling, windows of your classroom, the blackboard.....its very simple to identify a quadrilateral.The word Quadrilateral is made of the words quad (meaning "four") and lateral (meaning "of sides").
We can learn about Quadrilaterals by studying the objects around us as mentioned in the above example.The other way to understand quadrilaterals is by understanding the properties of a quadrilateral.

Let us now learn about the properties of a quadrilateral:

The sum of the angles of a quadrilateral is 360ยบ.The other thing we must keep in mind while learning quadrilateral is that quadrilateral are of different shapes and sizes.
Rhombus:
A Rhombus or rhomb is a quadrilateral whose four sided all have the same length.The rhombus is often called a Diamond
Rectangle:
A rectangle is any quadrilateral with four right angles
Parallelogram:
A parralellogram is a quadrilateral with two pairs of parallel sides. In Euclidean Geometry, the opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
Hope you like the above example of Quadrilaterals
