Exercise 13.1
1. List any four symmetrical objects from your home or school.
Answer
Notebook, Blackboard, Glass, Inkpot.
2. For the given figure, which one is the mirror line, l1 or l2?
Answer
l2 is the mirror line as both sides of the lines are symmetric.

Answer
(a) Symmetric
(b) Symmetric
(c) Not Symmetric
(d) Symmetric
(e) Symmetric
(f) Symmetric
4. Copy the following on a squared paper. A square paper is what you would have used in your arithmetic notebook in earlier classes. Then complete them such that the dotted line is the line of symmetry.
5. In the figure, l is the line of symmetry.

(b) A quadrilateral with both horizontal and vertical lines of symmetry.
(c) A quadrilateral with a horizontal line of symmetry but no vertical line of symmetry.
(d) A hexagon with exactly two lines of symmetry.
(e) A hexagon with six lines of symmetry.
(Hint: It will be helpful if you first draw the lines of symmetry and then complete the figures.)
Answer

3. In each figure below, a letter of alphabet is shown along with a vertical line. Take the mirror image of the letter in the given line. Find which letters look the same after reflection (i.e., which letters look the same in the image) and which do not. Can you guess why?
Try for O E M N P H L T S V X
Chapter 13 Symmetry NCERT Solutions will prepare students to do better during immense pressure. A figure can have line symmetry if a line can be drawn dividing it into two equal halves.
• Objects that show line symmetry appear more balanced and beautiful.
• A shape may have just one or more than one lines of symmetry.
