In all these videos on Quadrilaterals from class 9th chapter 8 I have always focused on explaining the basics and then solving the questions. My way of solving question will always refer back to the basics explained previously so that students can make the connect between basics and application of them.
Let’s now start about the Quadrilaterals from class 9th chapter 8:
In this chapter of Quadrilaterals, we will talk about the different types of Quadrilaterals and their specification.

Once we know the types of quadrilaterals, we will move into the theorems part and then we will start solving the questions from each exercise.

Types of Quadrilaterals:

Parallelogram
Rhombus
Rectangle
Square
Trapezium
Isosceles Trapezium
Kite

Theorems:
Diagonals of a parallelogram divides it into two congruent triangles
In parallelogram opposite sides are equal
Diagonals of a parallelogram bisect each other
Line segment joining the mid points of two sides of a triangle is parallel and half of the third side
