Question

John notices that a standard piece of paper is a rectangle, how many lines of symmetry does it have?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is B 2

A line of symmetry is a line that divides a figure into two corresponding parts, each of which is the mirror image of the other.

In case of rectangle, vertical and horizontal line which meet at the center of the rectangle are line of symmetry.

hence vertical and horizontal line which passes through the center of the rectangle are $2$ line of symmetry of any rectangle.
