Important Topics for NCERT Maths Exemplar Solutions Chapter 5 – Understanding Quadrilaterals and Practical Geometry


In this chapter, you will learn about polygons. A polygon is a simple line segment which is a closed curve and is made only out of line segments. The chapter will further introduce you to various types of polygons and there will also be a discussion about the sides, diagonals, and characteristics of each of them. These explanations are provided in a detailed manner along with diagrammatic representation and examples. Parallelograms, rhombus, triangles, octagon, etc. belong to the category of polygons.


The vertices of a polygon that are non – consecutive are joined with the help of a line segment which is termed as a diagonal. The number of diagonals varies according to the number of sides in the given polygon. It is considered as an important characteristic in determining the unique factors of every polygon. These diagonals are also used as an essential factor in numerous formulas and calculations.

Convex Polygons and Concave Polygons 

Convex polygons are the figures that are discussed commonly like a triangle, a rectangle, a rhombus. These basically have a defined term and their sides bulge in the outwards direction. In the case of a concave polygon, their sides bulge towards their interior direction. Concave polygons usually do not have set names however they might appear in questions as the complex figures. In this chapter, you will only deal with convex polygons and their characteristics. The exercises also revolve around the convex polygons like rectangle, triangle, quadrilateral, etc.
