Question

What do we actually mean by a figure having two lines of symmetry?

• A. There exist only one line with respect to which the two halves are mirror images of each other.
• B. There exist two different lines in the figure with respect to which the respective halves are mirror images of each other.
• C. There exist two different lines in the figure with respect to which the respective halves are not mirror images of each other.
• D. There does not exist any line from where the halves are mirror images of each other.

Answer 1

The correct option is B

There exist two different lines in the figure with respect to which the respective halves are mirror images of each other.

By two lines of symmetry we mean that two different lines in the figure can be drawn with respect to which the halves are mirror images of each other.

Eg. Rectangle, the alphabet 'X' etc.
