Vectors

Represent and calculate with vectors — addition, subtraction, scalar multiples, and geometric proofs.

Vector Addition, Subtraction, and Scalar Multiplication

Combine vectors using addition and subtraction, and scale them with a constant — the building blocks of vector geometry.

Vector Basics

Understand what vectors are, how to write and represent them, and the difference between a vector and a scalar.

Vector Geometry Proofs

Use vectors to prove geometric results — parallel lines, midpoints, and that points are collinear.
