## NCERT Solutions for Class 6 Maths Chapter 5 Understanding Elementary Shapes (Ex 5.5) Exercise 5.5

The brief chapter “Understanding Elementary Shapes” to which the NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5 pertains, covers the idea of perpendicular lines. Two lines are considered to be perpendicular to one another when they cross at right angles. There are just 4 questions in NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5. The English letter “T” is a good illustration of a perpendicular line that students may encounter frequently in everyday objects.Students will have to work hard to recognise perpendicular lines while working on NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5.. On the Extramarks website and mobile application, students can find the PDF versions of the NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5 which is centredon “Understanding Elementary Shapes.”

Through the NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5 the idea of perpendicular bisectors will also be introduced to students enclosed in Understanding Elementary Shapes. The perpendicular bisector design, however, will be covered in more detail later in the NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5. Students can participate in activities to better understand ideas with the aid of the NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5. For best outcomes, students should practise all of the exercises’ questions with the aid of NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5.

## NCERT Solutions for Class 6 Maths Chapter 5 Understanding Elementary Shapes (Ex 5.5) Exercise 5.5

Understanding Elementary Shapes in NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5 clarifies many ideas regarding the shapes students regularly encounter. Measuring Line Segments is the first topic covered in the NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5. In this part of the NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5, many comparison techniques will be examined, such as:

1. Observational comparison
2. Tracing comparisons
3. Evaluation with a division and a ruler

Below are a few points to remember before delving into the NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5:

• A line segment’s length is the distance separating its endpoints.
• The many tools for measuring length are described.
• A graduated ruler and divider are useful for comparing the lengths of line segments.

Further, the following angles that will be discussed in NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5 are:

• Right angle
• Straight angle
• Complete angle
• Acute angle
• Obtuse angle
• Reflex angle

The clock, instructions, ladder, and other examples from everyday life are used to explain concepts in the NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5. The relationship between revolution and right angles can be seen by using the example of a clock. The concept of measuring angles will also be covered in these NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5.Angles are quantified in terms of degrees. A protractor is a tool used to measure an angle. One has to know how to operate a protractor and what its many features, such as scales and a straight edge, are.

Other subjects covered in this NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5 include:

1. Perpendicular lines and perpendicular bisector: If two intersecting lines have an angle of 90 degrees or less, they are perpendicular.
2. Triangle classification: Triangles can be categorised according to their angles and side lengths.
• A Scalene Triangle is a triangle with all three unequal sides.
• An isosceles triangle is one that has two sides that are the same length.
• Equilateral triangles are triangles with three equal sides.
• The triangle is referred to as an acute-angled triangle if each angle is smaller than 90°.
• The triangle is referred to as having right angles if any one of its angles is one.
• The triangle is referred to as an obtuse-angled triangle if any one angle is more than 90°.
1. Quadrilaterals: These NCERT Solutions Class 6 Maths Chapter 5 Exercise 5.5 discuss various types of quadrilaterals, including:
• Rectangle
• Square
• Parallelogram
• Rhombus
• Trapezium
1. Polygons
2. Three-dimensional shapes:
• Prism
• Pyramid
• Sphere
• Cone
• Cylinder
• Cube and cuboid

## NCERT Solutions for Class 6 Maths Chapter 5 Understanding Elementary Shapes (Ex 5.5) Exercise 5.5

Curves or lines are used to create all shapes. Corners, edges, planes, open curves, and closed curves are a few of the shapes that humans encounter every day. Line segments, angles, triangles, polygons, and circles can be made using these shapes. Students will initially study Measuring Line Segments. In the future, they will learn several comparison techniques, including comparison by observation, comparison by outlining, and comparison using a ruler and divider. After that, they will study various angles, such as reflex angles, acute angles, complete angles, acute angles, and complete angles. In this section, angles are discussed in the Class 6 Maths Chapter 5 Exercise 5.5 Answers using examples such as a clock, a ladder, and directions.

The idea of measuring angles and the equipment used to measure angles will be the subject of the following discussion. Along with these Class 6 Maths Chapter 5 Exercise 5.5, students will study polygons, triangles, quadrilaterals, and perpendicular lines. Students can practise  Maths Class 6 Chapter 5 Exercise 5.5 by using the NCERT Solutions For Class 6 Maths Chapter 5 Exercise 5.5 centred on Understanding Elementary Shapes.

Q.1 Which of the following are models for perpendicular lines :
(a) The adjacent edges of a table top.
(b) The lines of a railway track.
(c) The line segments forming the letter ‘L’.
(d) The letter V.

Ans.

(a) The adjacent edges of a table top are perpendicular lines as they form a right angle.

(b) The lines of a railway track do not form a right angle. As they are parallel lines and forms a zero angle.

(c) The line segments of the letter ‘L’ are perpendicular lines as they form a right angle.

(d) The letter V do not form a right angle but forms an acute angle.
