Vectors
Vectors are simply lines. The only difference between a normal line and a vector is that vectors have the ability to be rotated, scaled and transformed.
Rotated simply means turned, transformed means moved and scaled means stretched.
The properties of a vector are its magnitute (length) and direction.
Now vectors make maths alot easier when it comes to proofs, and overall, are easier to work with.
Here are some tutorials on the mathematics behind vectors:
