R.D. Sharma Maths Solution for Class 8 Chapter 18 Practical Geometry

Practical Geometry is the 18th chapter in the R.D. Sharma Maths book for Class 8 and it provides in-depth knowledge of geometry to the students and makes it easier for the young minds to understand geometry in such a way that it piques their interest. Before quadrilaterals, students learned about the construction of triangles and it is just like that but with the addition of one more side and subsequent angle and diagonals.

The chapter is about the construction of quadrilaterals; how to construct them through the different elements given. To make it easier for students of Class 8, Vedantu provides solutions for each exercise and each class if the students get stuck somewhere while solving the questions. Class 8 is the stage where students start learning and adapting new things and this construction work would be interesting other than something boring as it requires them to draw but on a slight senior level.


Construction of Quadrilaterals

Four sides, four angles and two diagonals make up a quadrilateral. In the exercises afterward, the chapter teaches about how to construct them if one or more than one of these elements are missing. Various situations of constructing the quadrilaterals according to the given elements are listed below:

  • When one diagonal and four sides are given.

  • When there are three sides and two diagonals.

  • When there are four sides and one angle.

  • When three sides are given along with their included angles.

  • When three angles are presented, along with their two included sides.

FAQs on RD Sharma Class 8 Maths Solutions Chapter 18 - Practical Geometry

1. Is it easy to construct a quadrilateral?

Constructing a quadrilateral is, anyways, not a big task but when the five measures of a quadrilateral are specified, it is fairly simple to create one.

  • The four sides' lengths, as well as the diagonal length, are known.

  • The three sides' lengths, as well as the lengths of the two diagonals, are known.

  • If you know the three angles and two adjacent sides, you can solve the problem.

  • If you have three sides and two angles, you can make a triangle.

2. When can a unique quadrilateral be constructed?

We need at least five measurements of sides and angles to draw a unique quadrilateral. However, having the dimensions of any five combinations of sides and angles does not guarantee that we will receive a unique quadrilateral.

1. If we are given the measurements of four sides and one diagonal of a quadrilateral, we can design a unique quadrilateral.

2. If we are given the measurements of two diagonals and three angles of a quadrilateral, we will not be able to design a unique quadrilateral.

3. Is it important to solve every question of the exercises?

Yes, it is very important to solve all the questions of all the exercises because questions are never the same; there might be one or more than one change(s) in the question and any of such questions can come in your exam so you must have already solved it beforehand to solve in the examination as well. Apart from this, it also enhances your problem-solving ability and the practice you will be doing of solving every question will help you perform better in your exams as practice is everything.

4. What are some key points to remember for the chapter Practical Geometry?

There are many things that one should keep in mind while constructing quadrilaterals, a few of them are listed below:

  • It is necessary to know at least five independent elements to draw the quadrilateral properly.

  • With enough data (other than five simple situations), a quadrilateral can be constructed with less than five pieces but some other relationships between them.

  • Drawing a basic sketch of the quadrilateral and indicating the data on it is convenient and helpful in all circumstances.

5. How to construct a rhombus?

The rhombus itself is a quadrilateral and can be constructed by following some simple steps. To construct a rhombus, the steps are given below.

  • Draw a perpendicular bisector of the diagonal base and a diagonal of a given length.

  • Cut off arcs on both sides of the perpendicular bisector with half of the supplied measurement of the second diagonal. It will yield two rhombus points.

  • Connect these points to the first diagonal points. It will produce the rhombus that is necessary.
