PreCalculus Geometry Notes
These notes on Precalculus: Geometry and Functions I introduce essential geometric concepts, from lines, angles, and transversals to the Pythagorean theorem, coordinate planes, and functions. They progress to graphs, isometries, mappings, and trigonometry, including radian measure, sine, cosine, and addition formulas, with exercises throughout to build problem-solving skills. Appendices provide deeper insights into mass points, center of mass, and vectors for advanced geometric applications.
