Kyle tested different mirrors for the fun house he was designing. Kyle decided to use three different mirrors – one that did not distort objects, one that made objects look taller, and one that made objects look much smaller. What can you infer about these mirrors? 10 pts A mirror not curved does not distort objects. A concave mirror makes objects taller. A convex mirror makes objects smaller.
