Question

What is a Trapezium?

Answer 1

Hint: Trapezium is a polygon. A polygon is a plane figure with at least 3 or more ‘straight’ lines.

Complete step-by-step answer:

It comes under the category of Quadrilaterals, which means that it has 4 sides.
Let us now know about Quadrilaterals and Polygons.
POLYGON: A polygon is a ‘2 – dimensional shape’ that is formed with straight lines. Triangles, quadrilaterals, pentagons, hexagons, etc. are some examples of polygons.
QUADRILATERAL: A quadrilateral can be defined as a closed, two – dimensional shape which has four straight sides. Therefore, it is a polygon.
The polygon has four vertices, i.e. four corners.
For example: Square, Rectangle, Rhombus, Trapezium, Parallelogram, etc .

Trapezium is a 2D shape which has 4 sides and it is a polygon. A 2D figure or shape is a two -dimensional shape that can be defined as a flat plane figure or a shape that has two dimensions – length and width. Two-dimensional or 2-D shapes do not have any thickness and can be measured in only two faces. In other words, we can say that a 2-D shape can be obtained on a plane paper. As mentioned in the hint, a polygon is a plane figure which has at least 3 or more ‘straight’ lines.
Any of the 2 pairs of sides of a trapezium are parallel. Now the word parallel means that even when their length is increased, i.e. when they are extended from both the sides, they would not intersect each other. Intersect means that when any 2 lines cross each other in a plane, they are called intersecting lines and we can say that they intersect each other.

Note:- It must be noted that only a pair of its sides, i.e. only 2 of its sides are parallel, which means that they will never intersect each other. The other pair of its side, i.e. its other 2 sides is not parallel, which means that on extending their lengths, they will intersect each other.
