In this final video on measurement of angles we will go over 2 final examples that require the use of algebra to solve.

Vector Man rescues a waiter from a burning restaurant, but forgets to put out the fire! This lesson will explain how to draw free body diagrams.<br/>
Definitions included: free body diagram, net external force

In this lesson, students will learn how to determine if a fence is parallel to a river by analyzing a diagram. By measuring the sides of triangles and comparing their ratios, they can determine if the fence is parallel.
