Subtracting Two Vectors Geometrically

Find vector C (with its tail at the origin) such that C = A - B.
To do this:

  • 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 to be.
  • Click "Score" to see how you did. If you are correct, your vector will be labeled.
    Your answer must be 8% of the correct answer.
