This document contains information about a geometry lesson on angle of elevation and depression, including homework assignments, pages from notebooks and textbooks to reference, and reflection questions about the lesson. The reflection questions ask about why angles of elevation and depression are the same, strategies for solving these types of problems, and professions that use trigonometric ratios to determine heights and distances.

8-4 Reflection Questions
#1. Why is the angle of depression from a light house to a boat the same as the angle of
elevation from the boat to the light house?
The angle of depression from the lighthouse and the angle of elevation from the boat are
alternate interior angles formed by the line of site (the transversal) and the parallel
horizontal lines.
#2. What strategy is used to solve angle of elevation and depression problems?
#3. Comment on who might use trigonometric ratios to solve angle of depression and
elevation problems and how?
