Understand that a two‐dimensional figure is congruent to another if the second can be obtained from the first by a sequence of transformations. Choose all that correctly describe a sequence of transformations which moves the pre-image onto the image and shows that the pre-image and image are congruent. Rotation 90° counterclockwise around the origin then, Translation (x, y) ↦ (x, y + 16) Reflection across the line x = −1 then, Rotation 270° counterclockwise around the origin Translation (x, y) ↦ (x + 15, y) then, Reflection across the x-axis Rotation 180° counterclockwise around the origin then, Reflection across the x-axis
