Dilations And Similarity Basics - Quiz

Are you ready to see how shapes can grow or shrink but keep the same look? In this quiz, you’ll learn what a dilation does, how a scale factor changes size, and why angles stay the same while sides stay in proportion. You’ll practice resizing shapes by multiplying their coordinates... see moreby a scale factor, figure out if the dilation makes them bigger or smaller, and see how this creates similar figures. see less
