MATH 123:Vectors and Geometry

 Vectors may be used very neatly to prove several theorems of geometry. This course is about applying  vector operations and the method of mathematical proof (of MATH 121) to geometric problems. The areas of study include:vector operations with geometric examples; components of a vector and the scalar product of vectors. Coordinate geometry in the plane including normal vector to a line, angle between intersecting lines, reflection in a line, angle bisectors and the equation of a circle, the tangent and the normal at a point.
