## 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
