**Symmetry**

**Question 1.List any four symmetrical objects from your home or school.**

**Solution:**List of four symmetrical objects from home or school are

**(i)**An electric tube

**(ii)**A glass

**(iii)**An electric bulb

**(iv)**A fan

**Question 2.For the given figure, which one is the mirror line, l _{1} or l_{2}**

**Solution:**

From the given figure, clearly l

_{2}is the mirror line.

**Question 3.Identify the shapes given below. Check whether they are symmetric or not. Draw the line of symmetry as well.**

**Solution:**

Figures (a), (b), (d), (e) and (f) are symmetrical and their line of symmetry is shown as a dotted line.

**Question 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.**

**Solution:**

Keeping the dotted line as the line of symmetry and completing the figure, we have

**Question 5.In the figure, l is the line of symmetry. Complete the diagram to make it symmetric.**

**Solution:**

Complete diagram is as under:

**Question 6.In the figure, l is the line of symmetry. Draw the image of the triangle and complete the diagram so that it becomes symmetric.**

**Solution:**

The image of the triangle is shown such that the complete diagram becomes symmetric.
