NCERT Solutions for Quadrilaterals Exercise 8.2 Class 9 Maths: Overview

If no three points out of four are collinear, the figure so created is a closed figure with four sides. Such a figure formed by joining four points in order is called a quadrilateral. In the ex 8.2 Class 9, students are required to prove that two sides are parallel to each other and one side is half of the other side and that the whole figure is a parallelogram.

From the given information, prove that the given figure is a rectangle, or a rhombus, from the given information, prove that a certain point is the mid-point of a side.
