Area of Trapezium
Before you study what is trapezium, you are advised to read:
What is Quadrilateral ?
What are Parallel Lines ?
Trapezium is a quadrilateral in which a pair of sides is parallel to each other.
Or we can say, Trapezium is a quadrilateral having a pair of parallel sides.
We can also say that:
In Trapezium, two opposite side are parallel and other two opposite sides are unparalleled.
Observe the following diagram 1:
In the above diagram, you can observe that:
ABCD is quadrilateral
Side AD is parallel to Side BC (symbol '|' indicate parallel lines)
Side AB and DC are non parallel
Hence, we can say that Quadrilateral ABCD is a trapezium.
Following are some more sample diagrams of trapezium:
Trapezium PQRS has PS and QR as parallel lines (symbol '|' indicate parallel lines)
Trapezium MNOP has PM and NO as parallel lines (symbol '|' indicate parallel lines)
Trapezium WXYZ has WX and YZ as parallel lines (symbol '|' indicate parallel lines)
