It is rotation. when you move it upside down, it looks the same

Answer:

Any of ...

  • rotation 180° about the center of symmetry
  • reflection across the horizontal and vertical lines through the center of symmetry, in either order
  • reflection across any horizontal line, translation to the left, and translation up or down to final position (depending on where the horizontal line is)

Explanation:

The question is asking you what combinations of rotation, reflection, translation, and dilation will make the W have the position, orientation, and size of the M.

The image (M) is the same size as the preimage (W), so no dilation is involved.

The up-down orientation of the image is opposite that of the preimage, so reflection across a horizontal line, or rotation 180° will be involved. Depending on the line of reflection or the center of rotation, translation to the final image position may be required.

The preimage is symmetrical about a vertical centerline, so translation left or right can also be accomplished by reflection about a suitable vertical line.

_____

If you have trouble visualizing this, it can help to cut the letter from a piece of paper and manipulate it to model rotation, reflection, or translation.
