Assertion Reason Questions on Symmetry
Directions:
In the questions given below, there are two statements marked as Assertion (A) and Reason (R).
Read the statements carefully and choose the correct option:
(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.
Q1. Assertion (A): A figure has line symmetry if it can be folded into two identical halves.
Reason (R): In line symmetry, one half is the mirror image of the other.
Difficulty Level: Medium
Ans. Option (A) is correct.
Explanation: Both are correct and directly related. Folding into mirror halves defines line symmetry.
Q2. Assertion (A): All figures that have line symmetry also have rotational symmetry.
Reason (R): Some figures can have both line and rotational symmetry.
Difficulty Level: Hard
Ans. Option (B) is correct.
Explanation: While both are true independently, not all figures with line symmetry have rotational symmetry (e.g., letter “A”). So reason doesn’t explain the assertion.
Q3. Assertion (A): A square has four lines of symmetry and four angles of rotational symmetry.
Reason (R): The smallest angle of symmetry for a square is 90°.
Difficulty Level: Medium
Ans. Option (A) is correct.
Explanation: Both statements are true and connected. 90° is the smallest rotation where a square maps onto itself.
Q4. Assertion (A): A figure that rotates and looks exactly the same at 360° has rotational symmetry.
Reason (R): Every figure has 360° as an angle of symmetry.
Difficulty Level: Hard
Ans. Option (D) is correct.
Explanation: While the reason is true, the assertion is false because rotational symmetry requires at least one angle less than 360°. A figure with only 360° rotation doesn’t qualify.
Q5. Assertion (A): A circle has infinite lines of symmetry and infinite angles of rotational symmetry.
Reason (R): Any diameter can be a line of symmetry, and any degree of rotation keeps the circle unchanged.
Difficulty Level: Medium
Ans. Option (A) is correct.
Explanation: This is a unique property of circles. Both statements are true and reason perfectly supports the assertion.
