# Geometry B

### Why Take This Course?

Geometry has been a key element of the liberal education of thousands of leaders. Because of its visual and intuitive nature, it is one of the most accessible ways to learn the art of a mathematical proof. In Geometry B, we will refine our ability to think and reason logically as we study the same geometry texts that leaders like Hamilton and Lincoln used. In addition to learning about geometry topics, we will also explore topics from trigonometry and probability throughout the semester.
