A brief introductory course in plane geometry. Covers the topics from elementary geometry that are most likely to be required for more advanced mathematics courses. The only prerequisite is a semester of algebra.
Emphasis is on applying basic geometric principles to the numerical solution of problems. For this purpose the number of theorems and definitions is kept small. Proofs are short and intuitive.

Introduces students with a little algebra background to a few of the ideas of algebraic geometry and helps them gain some appreciation both for algebraic geometry and for origins and applications of many of the notions of commutative algebra.
