Basics Geometry
... Beyond the Basics Now we can use point, line, and plane to define new terms. Space: The set of all points expanding in three dimensions. Think back to the plane. It goes up and down, and side to side. If we add a third direction, we have space, something three-dimensional. Collinear: Points that lie ...

... into examples that show how the central angles create a full circle, so you can divide 360° by how many central angles the polygon has. Show an example with a triangle and have students create and measure exterior angles. Total the three angles up and then do another example with a rectangle. Studen ...

History of geometry
Geometry (from the Ancient Greek: γεωμετρία; geo- ""earth"", -metron ""measurement"") arose as the field of knowledge dealing with spatial relationships. Geometry was one of the two fields of pre-modern mathematics, the other being the study of numbers (arithmetic).Classic geometry was focused in compass and straightedge constructions. Geometry was revolutionized by Euclid, who introduced mathematical rigor and the axiomatic method still in use today. His book, The Elements is widely considered the most influential textbook of all time, and was known to all educated people in the West until the middle of the 20th century.In modern times, geometric concepts have been generalized to a high level of abstraction and complexity, and have been subjected to the methods of calculus and abstract algebra, so that many modern branches of the field are barely recognizable as the descendants of early geometry.
