  4.  • 1. Traditional Liberal Arts: Quadrivium - astronomy, • arithmetic, geometry, and music; Trivium - logic, • rhetoric, and grammar 2. Geometry and its descendant, trigonometry, are essential tools in engineering, architecture, navigation, and other disciplines. 3. We can learn how to draw valid conclusions from hypotheses and how to detect and avoid invalid reasoning. 4. Geometry is also beautiful, and some of its theorems are so amazing as to seem almost miraculous.

  5. Geometries • Euclidean Geometry • Computational/Algorithmic Geometry • Affine Geometry • Inversive Geometry • Projective Geometry • Fractal Geometry • Finite Geometry • Non-Euclidean Geometry • Descriptive Geometry • Analytical Geometry • Differential Geometry • Topology • • •

  9. Gougu Theorem While it is not known as to on what basis Pythagoras derived this theorem, this ancient Chinese proof clearly shows that the people in the ancient east were very much aware of this theorem well before Pythagoras. (In fact, the earliest known proof of this theorem was provided by the ancient Indian Vedic mathematicians, more than 2000 years before Pythagoras.) 1000 B.C.E.
