Answer:
Relative size
Explanation:
Relative size refers to the verity that the more far-away an object, the lesser in size the image will be on the retina. Hence, if there are dual matching objects, the one that is farther away in distance will be the object that has a smaller image view on the retina.
Humans also use relative size to determine the size of the earth natural satellite (moon). This is why it looks larger and closer when it is near the horizon than when it is high up there in the sky.
