Adding and Subtracting Vectors
You can use two methods to add or subtract vectors geometrically:
- The parallelogram method
- The tip-to tail (or head-to-tail) method.
Discover the two methods in the apps below.
The Parallelogram Method
The Tip-to-Tail (Head-to-Tail) Method
Glossary
Two vectors are equipollent (or equivalent) when they have the same magnitude and the same direction, regardless of their initial point.
Special Cases
Is it possible to apply the Parallelogram Method when the given vectors are collinear? Explore these special cases using the app, then explain your conclusions. (Note: Two vectors are collinear when they have the same direction, that is, they geometrically belong to the same line.)
