Video Summary

Thomas can shade two additional squares on the diagram to create a single axis of symmetry in six different ways. Each square has four possible axes of symmetry: horizontal, vertical, diagonal from top-left to bottom-right, and diagonal from bottom-left to top-right. For the first three axes, only one way exists per axis to complete the square for symmetry. For the diagonal axis from bottom-left to top-right, three extra squares on the line of symmetry can be shaded to maintain symmetry, allowing for three ways. Adding these possibilities (1+1+1+3) yields six ways, answer E.
