A reflection of shape I across the y-axis, followed by a ( ) , and then a translation left 6 units and down 4 units confirms congruence between shape I and shape II.

Alternatively, a ( )
of shape II about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape II and shape I.
