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.
