Geometry is one of the oldest sciences. Initially a body of practical knowledge concerning lengths areas , and volumes , in the third century B.C., geometry was put into an axiomatic form by Euclid , whose treatment - Euclidean geometry - set a standard for many centuries to follow. The field of astronomy , especially mapping the positions of the stars and planets on the celestial sphere, served as an important source of geometric problems during the next one and a half millennia. Introduction of coordinates by René Descartes and the concurrent development of algebra marked a new stage for geometry, since geometric figures, such as plane curves , could now be represented analytically , i.e., with functions and equations. This played a key role in the emergence of calculus in the seventeenth century. Furthermore, the theory of

Philosophy is written in this grand book - I mean universe - which stands continuously open to our gaze, but which cannot be understood unless one first learns to comprehend the language in which it is written. It is written in the language of mathematics, and its characters are triangles, circles and other geometric figures, without which it is humanly impossible to understand a single word of it; without these, one is wandering about in a dark labyrinth.

    Extractions: Geometry introduces geometric reasoning as a method for problem solving. Throughout the first nine sessions, you will explore the properties of geometric figures, make constructions using pencil and paper and dynamic software, practice using mathematical language to express ideas and justify your reasoning, and begin to explore the basis of formal mathematical proofs and solid geometry. The course material progresses from more visual, intuitive ways of solving problems to more formal explorations of geometric ideas, properties, and, finally, proofs. The 10th session explores ways to apply the concepts of geometry you've learned in K-8 classrooms. Watch the Videos Online Support Materials Channel Talk

The geometry skills and concepts developed in this discipline are useful to all students. Aside from learning these skills and concepts, students will develop their ability to construct formal, logical arguments and proofs in geometric settings and problems. Students demonstrate understanding by identifying and giving examples of undefined terms, axioms, theorems, and inductive and deductive reasoning. Students write geometric proofs, including proofs by contradiction.
