## NCERT Solutions for Class 7 Maths Chapter 14 Symmetry Ex 14.1

**Question 1.**

Copy the figures with punched holes and find the axes of symmetry for the following :

**Solution:
**

**Question 2.**

Given the line(s) of symmetry, find the other hole(s) :

**Solution:
**

**Question 3.**

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 ?

**Solution:**

**Question 4.**

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 :

**Solution:
**

**Question 5.**

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?

**Solution:
**

Yes! there is more than one way to make the figure symmetric.

**(i)**Let us take the diagonal BD and shade the squares as shown in the figure to make the figure symmetric about BD.

**(ii)**Similarly, the figure is symmetric about the diagonal AC.

Thus, the figure is symmetric about both the diagonals.

**(iii)**The figure is symmetric about EF and GH also.

**Question 6.**

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

**Solution:
**

**Question 7.**

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.

**Solution:
**

**Question 8.**

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.

**Solution:
**

**Question 9.**

Give three examples of shapes with no line of symmetry.

**Solution:
**

**(b)**A scalene triangle,

**(c)**A parallelogram

**Question 10.**

What other name can you give to the line of symmetry of

**(a)** an isosceles triangle?

**(b)** a circle?

**Solution:**

**(a)** Median

**(b)** Diameter.
