Category: Mathematics
Credits: 10
Recommended Grades: 9,10,11

Description: This course is intended for students who took, but did not receive credit for Geometry (FAILED). In this course, students grapple with precise geometric definitions and theorems in the language of mathematics. Students undergo a rigorous analysis of shapes with an emphasis on triangles, quadrilaterals, and circles. This analysis requires exploring and investigating transversals, transformations, congruence, similarity, basic trigonometry, area/volume, probability, and much more. As the year progresses, students develop their ability to construct and critique mathematical arguments and eventually, proofs.
