Symmetry Class 6 Assertion and Reason Questions

In each of the following questions 1 to 5, two statements have been given. One has been labelled Assertion (A), and the other Reason (R). You have to choose the correct option from the four given options.

(a) Both statements (A) and (R) are correct, and (R) is the correct explanation of (A).

(b) Both statements (A) and (R) are correct, but (R) is not the correct explanation of (A).

(c) (A) is correct, but (R) is not correct.

(d) (R) is correct, but (A) is not correct.

1. (A): The has two lines of symmetry.

(R): The has one line of symmetry.

Answer:

(d) (R) is correct, but (A) is not correct.

2. (A): The angle of symmetry for the rotational symmetry of is 90°.

(R): By rotating the figure about its centre by each rotation of 90°, the figure coincides with its original position.

Answer:

(a) Both statements (A) and (R) are correct, and (R) is the correct explanation of (A).

3. (A): A parallelogram has a rotational symmetry of 180° rotation.

(R): A parallelogram has two lines of symmetry, as 360° ÷ 2 = 180°.

Answer:

(c) (A) is correct, but (R) is not correct.

4. (A): The figure has two lines of symmetry.

(R): The above figure has a rotational symmetry of order two.

Answer:

(b) Both statements (A) and (R) are correct, but (R) is not the correct explanation of (A).

5. (A): A regular heptagon has a rotational symmetry of order seven.

(R): A regular heptagon has seven equal sides and seven equal angles.

Answer:

(b) Both statements (A) and (R) are correct, but (R) is not the correct explanation of (A).
