Vector Proofs

Vectors can be used to prove geometric facts. Two vectors are equal only if they have identical components. Showing vector AB = vector DC proves that ABCD is a parallelogram, since this means the sides are parallel and equal in length.

Check whether two vectors are equal, or test your knowledge of vector proof facts.
