Polygons Solutions - Free PDF Download

The RS Aggarwal Class 6 math Chapter 15 is Polygons, which is part of Chapter 5, Understanding Elementary Shapes, of the NCERT textbook. It is important to understand the contents of the RS Aggarwal Class 6 math Polygons very well because it will act as a base for all the math we will do in higher Classes. If we do not understand the basics, we will not be able to understand the more complex topics we will do later on in higher Classes. Vedantu has provided RS Aggarwal solutions for Class 6 Chapter 15, Polygons, to ensure that students can build this base by understanding the concepts and solving questions.

All About RS Aggarwal Solutions for Class 6 Chapter

The other topics, apart from polygons, discussed in the NCERT Chapter ‘Understanding Elementary Shapes’ include line segments and how to measure them, right angles, straight angles, acute angles, obtuse angles, reflex angles, and how to measure all of these angles. The Chapter also discusses the concept of perpendicular lines, and how to Classify triangles into right, obtuse, acute, isosceles, scalene and equilateral. Finally, the Chapter comes to discuss quadrilaterals, which are polygons with four sides, and three-dimensional shapes like spheres, cones, cubes, cuboids, cylinders and pyramids. In the RS Aggarwal Class 6 Polygons, quadrilaterals, as well as other shapes with more than 4 sides, are discussed. Vedantu has provided solutions for this part of the Chapter in PDF for all students to use comfortably.

Explanation of RS Aggarwal Class 6 Polygons

A polygon refers to a figure which has a minimum of three sides and is made of line segments and angles. There are several kinds of polygons, the most basic one of which are triangles. Let’s look at some polygons and their properties.


  • Triangles can be right-angle triangles, obtuse triangles or acute triangles, depending on the kinds of angles that they are made up of. Triangles can also be equilateral (where all three sides are equal), isosceles (where two sides are of equal length and the third is not) and scalene (where all three sides have a different length).


  • Quadrilaterals are polygons that have four sides and they can come in various kinds depending on the angles and the lengths of the sides. Some quadrilaterals are parallelograms, kites, rhombus, trapeziums and of course, rectangles and squares.

Other Polygons

  • Pentagons are polygons which have five sides, hexagons are polygons which have six sides, heptagons have seven sides, octagons have eight sides, nonagons have nine sides, decagons ten sides, and so on.

  • Polygons can be regular, where all the angles are all acute, obtuse or right angles, but some can also be irregular and have reflex angles as well. However, it is only the number of sides or line segments in the polygon that we count to deem the kind of polygon which it is.

As mentioned before, RS Aggarwal Class 6 math Chapter 15 is part of the Chapter ‘Understanding Elementary Shapes’ in the NCERT textbook, so the weightage marks will be explained using the same.

The SA-1 question paper for Class 6 math is of 40 marks, out of which the Chapter ‘Understanding Elementary Shapes’ is under the unit of Geometry and the unit as a whole will come for 9 marks.

The SA-2 question paper for Class 6 math is of 70 marks, and out of this, 10 marks are assigned to the unit of Practical Geometry, the unit under which Geometry comes.

FAQs on RS Aggarwal Class 6 Solutions Chapter-15 Polygons

1. What are the Other Topics in the Chapter Covering Polygons?

The Chapter covering polygons in the NCERT math textbook for Class 6 is called ‘Understanding Elementary Shapes’ and it discusses various topics that slowly build-up to the last topic. The Chapter begins with discussing line segments, then angles and the different types of angles, triangles and the different kinds of triangles based on angle and side. Further, the Chapter discusses quadrilaterals (kite, rhombus, parallelogram, trapezium, square, rectangle), other polygons (pentagon, hexagon, hectagon, octagon), and finally three-dimensional shapes like cubes, cuboids, spheres, cones, pyramids, cylinders and also, prisms. This Chapter must be studied by students thoroughly, as it provides students with a base in geometry which they will be needing later on, in higher Classes while studying more complex geometry.

2. How many Marks do RS Aggarwal Class 6 Polygons Hold?

The summative assessment-1 (SA-1) for math in Class 6 holds 40 marks, and SA-2 holds a total of 70 marks. RS Aggarwal Class 6 math Polygons comes under Chapter 5 of NCERT, which is ‘Understanding Elementary Shapes’ and it comes under the unit of Geometry in SA-1 and Practical Geometry in SA-2. For summative assessment 1, the unit of Geometry holds 9 marks, and the marks for Polygons will be taken from this. The same goes for summative assessment 2, where the Practical Geometry unit accounts for 10 marks, out of which Polygons will also get its marks.

3. How is it beneficial to go for Vedantu for RS Aggarwal Class 6 Solutions Chapter-15 Polygons?
