More than 2000 years ago, long before rockets were launched into orbit or explorers sailed around the globe, a Greek mathematician measured the size of the Earth using nothing more than a few facts about lines, angles, and circles. This course will start at the very beginnings of geometry, answering questions like "How big is an angle?" and "What are parallel lines?" and proceed up through advanced theorems and proofs about 2D and 3D shapes.
In this course we will learn the basic properties, theorems, and proofs. But you will be your own teacher and discover these ideas through investigations and activities and you will decide your path of instruction.
