Understanding Quadrilaterals
Chapter 11: JNVST Class 9 Understanding Quadrilaterals in Mathematics: Easy Explanation and Key Concepts
Look around you, and you will find many four-sided shapes, such as windows, books, and tiles. These shapes are called quadrilaterals. In Understanding Quadrilaterals in Mathematics, students explore these shapes and learn how their sides, angles, and properties are connected. The chapter covers different types of quadrilaterals and the basic rules used to solve questions.
It also introduces useful Quadrilateral formulas that can make calculations easier. For students following the JNV syllabus, a clear understanding of these concepts can make Maths practice simpler. With easy examples and key points, this chapter can also help students revise the topic before the JNVST Class 9 exam. With regular practice, students can also handle Navodaya Class 9 important questions with more confidence. Therefore, Veda Academy provides the best online classes for Navodaya Vidyalaya Class 9; along with this, they offer many practise papers separately in their Veda Academy Store for Class 9 students.
What Is a Quadrilateral?
A quadrilateral is a four-sided closed figure. Its four sides meet at four vertices. Its inside angles have a total of 360°. Squares, rectangles, rhombuses, parallelograms, trapeziums, and kites are common examples. Understanding quadrilaterals in mathematics becomes easier when you first learn basic parts.

Types of Quadrilaterals
Different quadrilaterals have different features. Below, we have discussed them. Look at the following.
Square: Four equal sides and four 90° angles.
Rectangle: Opposite sides are equal and four angles are 90°.
Rhombus: Four equal sides and equal opposite angles.
Parallelogram: Opposite sides are parallel and equal.
Trapezium: One pair of opposite sides is parallel.
Kite: Two pairs of adjacent sides are equal.
Therefore, Understanding Quadrilaterals in Mathematics is not only about names. It is also about knowing how each shape is different.
Important JNVST Class 9 Understanding Quadrilaterals in Mathematics Properties
A parallelogram has equal and parallel opposite sides. Its opposite angles are equal. A rectangle has four right angles. A rhombus has four equal sides. A square has four equal sides and four right angles. These Class 9 quadrilateral properties are easy to review.
For JNVST Class 9 Understanding Quadrilaterals in Mathematics, students should understand these facts instead of only memorising them. In addition, practise simple diagrams to make revision easier.
Key Quadrilateral Formulas
The main formulas are the perimeter of a quadrilateral, the area of a rectangle, the square, the sum of interior angles, and more. So, keep these quadrilateral formulas in a small revision notebook.
