Question

a chess board is shaped like a perfect square. select the image that shows all possible lines of symmetry on the chess board (1 point)

Explanation:

Step1: Recall square symmetry

A square has 4 lines of symmetry: 2 vertical/horizontal (through midpoints of sides) and 2 diagonal (through opposite vertices).

Step2: Analyze the image

The chessboard (square) should have these 4 lines. The shown image has 2 vertical/horizontal (dashed, mid - side) and 2 diagonal (dashed, vertex - vertex) lines, matching square's symmetry.

Answer:

The image with 2 horizontal/vertical (mid - side) and 2 diagonal (vertex - vertex) dashed lines (the one provided in the problem) shows all possible lines of symmetry for the square - shaped chessboard.
