In order to find the height of a cliff, you stand at the bottom of the cliff, walk 60 feet
from the base, and place a mirror on the ground. then you face the cliff and step back
5 feet so that can see the top of the cliff in the mirror. assuming your eyes are 6 feet
above the ground, explain how to use this information to find the height of the cliff.
(the angles marked congruent are congruent because of the nature of the reflection of
light in a mirror.)
