The dot product of a Cartesian coordinate system of two vectors is commonly used in Euclidean geometry. It also tells us how to parallel transport vectors between tangent spaces so that they can be compared. Parallel transport on a flat manifold does nothing to the components of the vectors, they simply remain the same throughout the transport process. This is why we can take any two vectors and take their dot product in $\mathbb{R}^n$.I know that if two vectors are parallel, the dot product is equal to the multiplication of their magnitudes.
