Course Description:

The fundamental purpose of the Geometry course is to formalize and extend students’ geometric experiences from the middle grades. In this Geometry course, students explore more complex geometric situations and deepen their explanations of geometric relationships, presenting and hearing formal mathematical arguments. Students will establish criteria for congruence of triangles based on rigid motions; establish criteria for similarity of triangles based on dilations and proportional reasoning; informally develop explanations of circumference, area, and volume formulas; apply the Pythagorean Theorem to the coordinate plane; and prove basic geometric theorems; and (6) extend work with probability.
