A quadrilateral can be defined as a particular shape that is two dimensional and consists of four sides. Quadrilaterals may seem to look like polygons that have four corners. The topic of quadrilaterals is a part of geometry, and to understand the concept in detail it is highly recommended to add RD Sharma Solutions in your study material.
How to Identify a Quadrilateral?
It is evident from the name itself that quadrilaterals will have four sides. But the question that arises here is, how will the students identify the quadrilaterals? There are two factors that are considered of prime significance to distinguish any random shape from a quadrilateral: the length and the angle.
Quadrilateral vs Square
As a quadrilateral has four sides it can be considered a square, and we all know that the sides of a square will be of equal length. Then, what is the difference between a square and a quadrilateral?
The basic difference between a square and a quadrilateral is that the square is a quadrilateral with equal sides and right angles. A square is just a type of quadrilateral. In the case of a square, one diagonal line must bisect the other one at right angles, which means the point at which the two diagonal lines will cross each other, the measurement of angle on that particle point will be 90 degrees.
The other criteria of a square are that the length of all four sides should be equal and the four angles should be 90 degrees. Also, the opposite sides should be parallel to each other.

1. What are the primary rules to identify a particular shape as a quadrilateral?
There are some rules that the students need to know before identifying a particular two-dimensional shape as a quadrilateral. Though quadrilaterals have some resemblances with polygons, all polygons cannot be considered quadrilaterals because there are some criteria that need to be fulfilled. First of all, the quadrilaterals must have four sides in a closed shaper and four angles whose sum should be 360 degrees. The opposite sides of the quadrilateral must be parallel to each other.
2. How to identify a quadrilateral?
A quadrilateral is called so because it has four sides that are congruent and four angles. In order to be identified as a quadrilateral, any two-dimensional shape needs to have four sides that must be parallel to each other and must have four angles that must be right angles, which means each of the angles should be 90°. It is quite evident from the answer that measuring the angles between the sides of a quadrilateral accurately plays a very important role in identifying the same.
3. Why is understanding the concept of quadrilaterals important?
The concept has been introduced in the syllabus of the students who are preparing for the class 9 examinations and this chapter is very important. Introducing this concept to the students at an early age will ensure that they will never forget the concept and ideas associated with the subject matter.
Identifying various geometrical shapes including quadrilaterals is very important for those who are planning to study engineering and architecture. The basic knowledge of all these shapes will come in handy for those students who will design floor plans while studying engineering.
4. Can the students join live classes on Vedantu in order to clarify their doubts?
Vedantu is a one-stop solution for students who face difficulties in understanding concepts and need expert guidance and suggestions to learn the subject in a better manner. Students can join live classes to get the true experience of digital classrooms and at the same time, they can clarify their doubts by asking their queries once the classroom session is over. The mentors will also provide printable and downloadable documents in PDF format that will make their learning process easier and organised.
