Subtracting Two Vectors Geometrically
Find vector C (with its tail at the origin) such that C = A -
B. Drag each vector by the circle on its tail to the appropriate position.
Click "Lock" to lock the positon of the vectors. (A red circle will appear
at the origin).
Drag the red circle to where the tip of the arrow representing the sum ought
Click "Score" to see how you did. If you are correct, your vector will be
To do this:
Your answer must be ±8% of the correct answer.
