Applied Geometry

Pre-Requisites

Algebra I Part I

Description

This sophomore level course is designed to emphasize the study of the properties and applications of common geometric figures in two and three dimensions. It also includes the study of transformations. Inductive and deductive thinking skills are used in writing proofs to solve (prove) properties of geometric figures.
