## NCERT Class 6 Maths Chapter 5: Important Topics

Chapter 5 comprises various fundamental concepts. All topics and subtopics covered CBSE, NCERT Class 6 Maths Chapter 5 Solution have been listed below.

**Introduction to Understanding Elementary Shapes**

This section introduces you to different elementary shapes such as line segments, angles, and their types, triangles, and their classifications, polygons, quadrilaterals, and three-dimensional shapes.

**Measuring Line Segments**

This part of the chapter talks about the ways of measuring a line segment. A line segment is a portion of a line that can be measured. The length of a line is the distance between two end-points. In this chapter, students learn about comparing two line segments based on Observation, Tracing, and Measurement using a ruler or divider.

**Angles and Its Types**

This portion of the CBSE, NCERT Solutions for Class 6 Maths Chapter 5 teaches you that every angle comprises two straight lines that meet at the same point. It also tells you how angles can be best understood from the movement of clock hands. It tells you how a straight line is 180 degrees while a right angle is always 90°. Here are the different types of angles covered in this section.

**Acute Angle****Obtuse Angle****Reflex Angle**

This section also teaches you about right angles and perpendicular lines and perpendicular bisectors.

**Triangles & Its Types**

This section of the chapter elaborates on the meaning of a triangle and its various types. A Triangle is

a closed figure that can be categorized as a polygon with the least number of sides. Triangles can be classified as various categories on the basis of angles, such as the following.

**Acute Angled Triangle****Right Angled Triangle****Obtuse Angled Triangles**

Triangles can also be classified on the basis of the length of the sides. The following are the classifications.

**Scalene Triangle****Isosceles Triangle****Equilateral Triangle**

**Quadrilaterals**

This part of the chapter teaches you that a quadrilateral is a four-sided polygon. It comprises four sides, two diagonals, and four angles. This section elaborates on the definition and properties of different types of quadrilaterals, such as Squares, Rectangles, Rhombus, Parallelogram, and Trapezium.

**Polygons**

This section of the chapter talks about the meaning and significance of Polygons. A polygon comprises at least three sides and three angles. It tells you that a polygon with three sides is known as a triangle, while a polygon with four sides is known as a quadrilateral. It teaches you about some common polygons classified on the basis of the number of sides, such as Pentagon, Heptagon, Hexagon, Decagon, Nonagon, Octagon, and Heptagon.

**Three-dimensional shapes**

Three-dimensional shapes that can be measured from all three directions that are length width and height are known as a 3D shape. Three-dimensional shapes include cubes, spheres, cuboids, cylinders, pyramids, cones, etc.
