Curriculum Burst 2: Angles in a Star
... I personally don’t feel too overwhelmed by this question as I am sure I can just start writing in angles. Something will probably come of it. (And if nothing does … I’ll panic then!) Let’s leap into it. I can see two angles I can write in right ...

... If two circles touch, the point of contact lies on the straight line joining their centers. From any point outside a circle two tangents can be drawn and they are equal in length. If a chord and a tangent intersect externally, then the product of the lengths of segments of the chord is equal to the ...

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.
