    Flag Pole

    For the flag pole:

    You could measure youself and your shadow.
    And the shadow of the flag pole.

    Then you could use similar triangles to find out how tall the flag pole is. Or you could use trig using the same information.

    1) Draw a parallel line along the river
    2) Mark the point on the line that forms a perpendicular line with a tree on the other side of the river
    3) Walk along the line for some distance "d" and note the angle "g" towards the same tree
    4) Use tangent.
