Trig River
Is it possible to determine the width of a river without crossing it?
Answer: It is possible to come very close to determining the width of a river of any size, using triangles.
The same principle used to determine the width of a river can be applied to other situations, including determining the height of a hill, a tree or a building. The simple geometric shape that makes this all possible is the triangle.
During this activity, you will learn how to use triangles to determine the width of a river.

Reflection:
This activity could be taken further by using a river or a building. Since the same process can be used the transition should be simple for students. In the future, this assignment could possibly be expanded to non-right triangles using different triangle characteristics to find the distance.
