A set of vectors whose span doesn't change after a transformation.

Since any vectors can be Basis Vectors, it's useful to understand how to translate vectors between bases

An object that describes a point and orientation relative to a BasePart

An operation between two 3d vectors that returns a vector.

A measure of how a matrix scales space.

The set of vectors that defines space.

In Roblox, a CFrame (coordinate frame) is an object that encodes position and rotation in 3D space.

When you multiply a matrix $(A)$ by the Identity Matrix $(I)$, you get the original matrix back.

$A …$
