I. Course Description
This course is a challenging, rigorous, proof-based approach to Geometry. Students in PSC analyze geometric
figures using deductive reasoning, make conjectures and formulate hypotheses, draw conclusions and make
connections with other mathematical concepts, and model situations geometrically as a problem solving
strategy. Algebraic and geometric skills are integrated throughout the curriculum.

V. Assignments & Grading
Assignment sheets will be distributed periodically throughout the school year. Homework will
be assigned on a daily basis. Grades will be based on quizzes and tests. In addition, teachers
may use homework, group activities, and/or projects for grading purposes. All students will take
departmental midyear and final exams. The Radnor High School grading system and scale will
be used to determine letter grades.
