MCQ 61 Mark

Assertion: There are infinite lines of symmetry of a circle.
Reason: The diameter is the mirror line of symmetry of a circle and there are infinite diameters possible for a given circle.

✓
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
B
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
C
Assertion is correct but Reason is incorrect.
D
Both Assertion and Reason are incorrect.

Answer

Correct option: A.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

There are infinite lines of symmetry of a circle because the lines of symmetry of a circle can be drawn from any angles. Another reason is that the diameter is the mirror line of symmetry of a circle and there are infinite diameters possible for a given circle. So, both the assertion and reason are correct and reason is the correct explanation for assertion.
