Important Topics covered in Chapter 8  Quadrilaterals
This chapter covers the important topics of quadrilaterals, its properties, and some key theorems.
8.1 Properties of a Parallelogram 
8.2 The MidPoint Theorem 
8.1 Properties of a Parallelogram  The properties of parallelograms are very useful when dealing with Polygon problems. The properties of a parallelogram are explained in detail in chapter 8 of NCERT solutions class 9 through illustrated problems.
Properties of quadrilaterals listed here and are wellused in NCERT solutions for class 9 maths chapter 8. The opposite sides of a parallelogram are parallel and equal to each other. The angles of the opposite sides are equal. Diagonals form congruent triangles with the sides of parallelogram, and the diagonals intersect each other. X is the angle between the diagonals and the vertices. eSaral Experts emphasize that the properties of the parallelogram are very important because it is the basic shape of other Quadrilaterals such as Rectangle, Rhombus and Square. In addition, all the properties of the parallelogram are used in certain proofs and problems solutions in the most efficient way in NCERT solutions provided by eSaral for class 9 chapter 8.
8.2 The MidPoint Theorem  In this section, you will learn that The line segment joining the midpoints of two sides of a triangle is parallel to the third side. In contrast, the third side is bisected by the line that is drawn through the center of one side of the triangle and parallel to the other side. NCERT Solutions for class 9 maths chapter 8 shows the detailed solutions to all the problems based on midpoint theorems. The NCERT solutions for class 9 maths chapter 8 covers all these involuted problems in an easytounderstand way for students.
Important Theorems Covered In NCERT solutions for Class 9 Maths Chapter 8  Quadrilaterals
To understand the concepts of quadrilaterals you need to learn the important theorems included in this chapter.

Theorem 1 : A diagonal of a parallelogram divides it into two congruent triangles.

Theorem 2 : In a parallelogram, opposite sides are equal.

Theorem 3 : If each pair of opposite sides of a quadrilateral is equal, then it is a parallelogram.

Theorem 4 : In a parallelogram, opposite angles are equal.

Theorem 5 : If in a quadrilateral, each pair of opposite angles is equal, then it is a parallelogram.

Theorem 6 : The diagonals of a parallelogram bisect each other.

Theorem 7 : If the diagonals of a quadrilateral bisect each other, then it is a parallelogram.

Theorem 8 : The line segment joining the midpoints of two sides of a triangle is parallel to the third side.

Theorem 9 : The line drawn through the midpoint of one side of a triangle, parallel to another side bisects the third side.

Frequently Asked Questions
Question 1. What are Quadrilaterals as defined in NCERT solution for class 9 maths chapter 8 ?
Answer 1. A quadrilateral, as defined by the NCERT solutions for class 9 maths chapter 8, is a plane figure consisting of four sides (or edges) and four vertices (or corners ). The most common quadrilaterals are those with four sides, such as rectangles, squares, trapezoids, kites, or irregular and indeterminate shapes.
Question 2. What is the relationship between trapezium and parallelogram ?
Answer 2. The parallelogram corresponds to the trapezium, whereas the trapezium does not correspond to the parallelogram.
