Answer:
A dilation is a type of transformation in which an image is enlarged or shrunk. This does not change the shape other than the fact that it is bigger or smaller.
Explanation:
Think of it this way: When Ant Man grows or shrinks, his hair doesn't change color or he isn't missing an arm or anything. Nothing about his body shape is changed- He is just smaller or bigger. That's essentially how a dilation works. Hope this helped!
