  # 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
