**Mathsight Class 7 Solutions Chapter 11 Symmetry**

Welcome to NCTB Solutions. Here with this post we are going to help 7th class students to solve MathSight Class 7 Mathematics Book, Chapter 11, Symmetry. Here students can easily get all the exercise questions solution for Chapter 11, Symmetry Exercise 11.1

**Symmetry Exercise 11.1 Solution : **

**Question no – (1)**

**Solution :**

**Question no – (2)**

**Solution :**

Reef angle, Square, Equilateral triangle.

**Question no – (3)**

**Solution :**

Parallelogram, Kite, Isosceles triangle have both line symmetry and rotational symmetry.

**Question no – (4)**

**Solution :**

Reef angle don’t have line of symmetry but have a rotational symmetry.

**Question no – (5)**

**Solution :**

Figure – **(a)**

= Order of rotational symmetry is 2

Figure – **(b)**

= Order of rotational symmetry is 4

Figure – **(c)**

= Order of rotational symmetry is 3

Figure – **(d)**

= Order of rotational symmetry is 5

**Question no – (6)**

**Solution :**

**(a)** the angle of rotational symmetry

= 360°/4

= 90°

**(b)** the angle of rotational symmetry

= 360°/2

= 180°

**(c)** the angle of rotational symmetry

= 360°/1

= 360°

**(d)** the angle of rotational symmetry

= 360°/3

= 120°

**(e)** the angle of rotational symmetry

= 360°/5

= 72°

**Question no – (7)**

**Solution :**

**Question no – (8)**

**Solution :**

**(a)** The figure is a Equilateral triangle.

**(b)** The figure is a Isosceles triangle.

**(c)** The figure is a Rhombus.

**Question no – (9)**

**Solution :**

**(a)** The statement is False.

**(b)** The statement is True.

**(c)** The statement is False.

**(d)** The statement is True.

**Question no – (10)**

**Solution :**

Horizontal symmetry = BOX

Vertical symmetry = WAX

**Question no – (11)**

**Solution :**

No, Because the clock are facing up wards, a clockwise turn would begin by rotating to the right.

Another side anti clockwise turn is in the opposite direction to the movement of the clock

**Question no – (12)**

**Solution :**

**(a)** clockwise.

**(b)** 360°

**(c)** No, number of turns of rotation should be decrease.

**(d)** 4
