1. What is the meaning of this signal?
(a) Round way (b) No left tern (c) Left turn allowed (d) U-turn
2. How many order of rotational symmetry it has?
(a) 2 (b) 3 (c) 4 (d) no order of symmetry

3. The direction of rotation of logo is:
(a) clockwise (b) anticlockwise (c) south (d) North
4. The number of times this logo coincides one full rotation in anti-clockwise direction is:

Directions for Questions 1 to 2: In each of the questions given below, there are two statements marked as
Assertion (A) and Reason (R). Mark your answer as per the codes provided below:
(a) Both A and R are true and R is the correct explanation of A.

(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false. (d) A is false but R is true.
Q. 1. Assertion (A): Circle has infinite line of symmetry.

Reason (R): The line of symmetry is a line that divides an object into two identical pieces.
Q. 2. Assertion (A): M has vertical line of symmetry.
Reason (R): Rotational symmetry, also known as radial symmetry in geometry, is the property a shape
has when it looks the same after some rotation by a partial turn.
Q. 3. Assertion (A): The letter O has only one lines of symmetry.

Reason (R): Symmetry can be horizontal and vertical.
Q. 4. Assertion (A): A regular hexagon with six equal sides has six lines of symmetry.

Reason (R): All regular polygons, the number of lines of symmetry is equal to the number of sides.
