### Geometry: An Interactive Journey to Mastery

Description
Geometry-in fact, mathematics as a whole-is an intensely human Enterprise. As its nae suggests, derived from the Greek ge for "earth" and metria for "measure," the subject evolved from very practical concerns: the art of accurately measuring tracts of land, performing feats of navigation, and accomplishing success in construction and architectural design, for example. But the study of geometry reveals a deep and rich layer of intellectual delight. Our human minds are drawn to elegance and beauty, both in the results of the hand and in the products of the dance between these two joyful pursuits, and this course is the journey of that dance for you to enjoy.
