Radnor High School Course Syllabus
Honors Geometry0428
Credits: 1 Grades: 9, 10Weighted: Yes Prerequisite: 8th Grade Algebra I with a "B" or Length: Year teacher recommendationFormat Meets daily
Overall Description of Course This course uses a disciplined approach to traditional Geometry, integrating the concepts and skills of the student's previous Algebra 1 course. Students in Honors Geometry apply geometric concepts to solve problems, use two-column proofs to establish relationships among triangles and parts of triangles, apply similarity theorems to geometric figures, relate knowledge of parallel and perpendicular lines to solve practical problems, combine algebraic and geometric skills to solve perimeter, area and volume problems, and apply skills involving trigonometry and transformational geometry.

Assignments & GradingAssignment 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.
