Question
Assertion (A): A rectangle has two lines of symmetry while a square has four.
Reason (R): A rectangle is not symmetrical about its diagonals.
✓

Answer

(a): A rectangle is symmetrical about the lines joining the midpoints of its opposite sides.
A square is symmetrical about the lines joining the midpoints of its opposite sides and also about its diagonals.
So, a rectangle has two lines of symmetry while a square has four.
$\therefore A$ is true.
$R$ is also true and $R$ is the correct explanation of $A$.
