You are standing 104’ from a flagpole with a mirror on the ground 4’ in front of you. Your eyes are 5.6’ off the ground. If you see the top of the flag pole in the mirror, how tall is the flagpole?

7-5 Proportional Parts and Parallel Lines Objective: Use proportional parts of triangles to solve problems, and divide segments by parallel lines

Triangle Proportionality Theorem If a line parallel to one side of a triangle intersects the other two sides then it divides the two sides proportionally.
