Two formulas for the dot product for use with geometric and algebraic vectors.  How to calculate the angle between two vectors that are tail to tail. How to tell if your vectors are perpendicular (ORTHOGONAL). Properties of the dot product and an example to show how to find an angle given a triangle on a coordinate plane (THINK position vectors FIRST) and how to use the properties of the dot product (see question 11 page 377).
