Final answer:
A translation demonstrates figures that are shifted or slid in a straight line, maintaining their shape and size, but changing their position. The correct answer is D).
Step-by-step explanation:
Figures demonstrate a translation when they are shifted or slid in a straight line without being rotated or reflected. Therefore, the correct answer is D) Figures that are shifted or slid in a straight line. This transformation involves moving every point of a shape the same distance in the same direction. A translation does not change the size or shape of the figure, meaning the translated figure will be identical in shape and size to the original figure. This means that after a translation, the figures will still have the same angle measurements and side lengths, maintaining correspondence between each point and its image.
