Question

how many lines of symmetry does a square have?

○ 2

○ 4

○ 3

○ 1

Explanation:

Step1: Recall line of symmetry

A line of symmetry divides a shape into two mirror - image halves. For a square, we consider different types of lines.

Step2: Identify lines of symmetry

• Vertical line: A vertical line passing through the mid - points of the top and bottom sides of the square. When we fold the square along this line, the left and right halves match.
• Horizontal line: A horizontal line passing through the mid - points of the left and right sides of the square. When we fold the square along this line, the top and bottom halves match.
• Two diagonal lines: The lines connecting opposite vertices of the square. When we fold the square along either of these diagonal lines, the two triangular halves match.

So in total, a square has 2 (vertical and horizontal) + 2 (diagonal) = 4 lines of symmetry.

Answer:

B. 4 (assuming the option with 4 is labeled as B, if the options are in the order 2,4,3,1 then the correct option is the second one which is 4)
