... • Remember, polygons will be similar when their corresponding sides all fit the same ratio. • That common ratio is called a scale factor. – We use the variable k to represent the scale factor. • So k = 3/2 or k = 2/3 , depending on which way you look at it. » Remember, it’s a ratio! ...

... Or we could do it by how many right angles they have. Like that weird trapezoid has 2 right angles. We could go by the ones that have parallel lines in them and the ones that don’t. We could do perpendicular lines and not perpendicular lines, because some of them don’t have any perpendicular lines a ...

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.
