Grade 7 Maths Ncert solutions for Symmetry

NCERT books are recommended text book for CBSE school curriculum. Most of the govt aided and private schools in India follow NCERT text books as the syllabus books for school subjects. They are written by eminent academicians and scholars from leading universities and academic institutions in India, and help in building a strong base, as well help understand each concept by relevant examples and exercises. They are termed best in term of concept building, for their usage of real life practical examples, and good end of the chapter exercises.

In this article, we have shared solved NCERT exercises for Class 7 maths symmetry chapter. These NCERT solutions will help students in solving their doubts and clarifying confusion regarding confusions regarding this chapter. Students can refer to NCERT solutions for symmetry chapter for their conceptual understanding, as well as matching their own answers with the right solutions of the exercises.

Class 7 math ncert solution symmetry chapter

Exercise 14.1 solutions

Q1 – Copy the figures with punched holes and find the axes of symmetry for the following: View solution

Q2 – Given the line(s) of symmetry, find the other hole(s): View solution

Q3 – In the following figures, the mirror line (i.e., the line of symmetry) is given as a dotted line. Complete each figure performing reflection in the dotted (mirror) line. (You might perhaps place a mirror along the dotted line and look into the mirror for the image). Are you able to recall the name of the figure you complete? View solution

Q4 – The following figures have more than one line of symmetry. Such figures are said to have multiple lines of symmetry. Identify multiple lines of symmetry, if any, in each of the following figures: View solution

Q5 – Copy the figure given here. Take any one diagonal as a line of symmetry and shade a few more squares to make the figure symmetric about a diagonal. Is there more than one way to do that? Will the figure be symmetric about both the diagonals? View solution

Q6 – Copy the diagram and complete each shape to be symmetric about the mirror line(s): View solution

Q7 – State the number of lines of symmetry for the following figures: (a) An equilateral triangle (b) An isosceles triangle (c) A scalene triangle (d) A square (e) A rectangle (f) A rhombus (g) A parallelogram (h) A quadrilateral (i) A regular hexagon (j) A circle View solution

Q8 – What letters of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about. (a) a vertical mirror (b) a horizontal mirror (c) both horizontal and vertical mirrors View solution

Q9 – Give three examples of shapes with no line of symmetry. View solution

Q10 – What other name can you give to the line of symmetry of (a) an isosceles triangle? (b) a circle? View solution

Exercise 14.3 solutions

Q1 – Name any two figures that have both line symmetry and rotational symmetry. View solution

Q2 – Draw, wherever possible, a rough sketch of (i) a triangle with both line and rotational symmetries of order more than 1. (ii) a triangle with only line symmetry and no rotational symmetry of order more than 1. (iii) a quadrilateral with a rotational symmetry of order more than 1 but not a line symmetry. (iv) a quadrilateral with line symmetry but not a rotational symmetry of order more than 1. View solution

Q3 – If a figure has two or more lines of symmetry, should it have rotational symmetry of order more than 1? View solution

Q4 – Fill in the blanks View solution

Q5 – Name the quadrilaterals which have both line and rotational symmetry of order more than 1. View solution

Q6 – After rotating by 60° about a centre, a figure looks exactly the same as its original position. At what other angles will this happen for the figure?  View solution

Q7 – Can we have a rotational symmetry of order more than 1 whose angle of rotation is (i) 45°? (ii) 17°? View solution

End Note

In the article, we have shared solutions for ncert exercises for class 7 maths for symmetry chapter. Students can click to respective chapters and refer to the right solution. We advise students to refer to them as clearing their concepts, and matching their solutions. Student should not use them to copy solutions for their homework and instead should try to solve homework on own, as it will impact their learning process.

In case you have any doubts regarding solution, or need further clarification, you can write to us. You can also reach out to us, in case you have doubt in other text books’ problems or school exam papers. We will be glad to assist you in helping with your doubt.
