Simply Easy Learning

Created by Megha Aggarwal, Last Updated 07-Aug-2019, Language:English

Description

The origin of the word "quadrilateral" is the two Latin word quadri a variant of four, and latus meaning "side". A quadrilateral is a polygon with four edges (or sides) and four vertices or corners. On certain conditions, Quadrilateral become either a Parallelogram or a Trapezium. Let us study those conditions in detail in this chapter.

Audience

These video lectures have been prepared exclusively for all English medium state board and central board class 9th students to have the understanding on basic properties of Quadrilaterals to become a Parallelogram.
