21. Geometry -- From Wolfram MathWorld geometry is the study of figures in a space of a given number of dimensions and of a given type. The most common types of geometry are plane geometry http://mathworld.wolfram.com/Geometry.html

Algebra Applied Mathematics Calculus and Analysis Discrete Mathematics ... Von Hendy Geometry Geometry is the study of figures in a space of a given number of dimensions and of a given type. The most common types of geometry are plane geometry (dealing with objects like the point line circle triangle , and polygon solid geometry (dealing with objects like the line sphere , and polyhedron ), and spherical geometry (dealing with objects like the spherical triangle and spherical polygon ). Geometry was part of the quadrivium taught in medieval universities. A mathematical pun notes that without geometry, life is pointless. An old children's joke asks, "What does an acorn say when it grows up?" and answers, "Geometry" ("gee, I'm a tree"). Historically, the study of geometry proceeds from a small number of accepted truths ( axioms or postulates ), then builds up true statements using a systematic and rigorous step-by-step proof . However, there is much more to geometry than this relatively dry textbook approach, as evidenced by some of the beautiful and unexpected results of projective geometry (not to mention Schubert's powerful but questionable enumerative geometry The late mathematician E. T. Bell has described geometry as follows (Coxeter and Greitzer 1967, p. 1): "With a literature much vaster than those of

Search Advanced Site Map A-Z Index Professional Development ... Printer-friendly version Geometry Grades Eight Through Twelve - Mathematics Content Standards. 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. Students construct and judge the validity of a logical argument and give counterexamples to disprove a statement. Students prove basic theorems involving congruence and similarity. Students prove that triangles are congruent or similar, and they are able to use the concept of corresponding parts of congruent triangles. Students know and are able to use the triangle inequality theorem.

Welcome! Customer Care Chat Login Subject Math > Geometry Geometry Geometry is a subject which starts from a point, goes to a straight line to planes, curved lines, curved surfaces and on to solid objects. It is a science where the answers to basic questions are only approximations but that does not hinder the most abstract concepts. Geometry needs to be taught properly and TutorVista has a wealth of tutors who are masters at this. Learn how to prove theorems, axioms and how to construct polygons, circles under expert tutelage.

EGYPTIAN GEOMETRY DETERMINING THE VALUE OF THE PYTHAGOREAN THEOREM Sacred Geometry? THIS PAGE IS UNDER CONSTRUCTION Unfortunately, a great many school children are misslead into believing as 3+1/8 using the observation below that the area of a circle of radius is "close to" the area of a square 8 units on a side. Until recently, Archimedes of Syracuse (250 BC) was generally consider the first person to calculate pi to some accuracy; however, as we shall see below the Egyptians already knew Archimedes (250B.C.) value of = 256/81 = 3 + 1/9 + 1/27 + 1/81, (the suggestion that the egyptians used = 3.1415 for <3+1/7 while in China in the fifth century, Tsu Chung-Chih calculate pi correctly to seven digits. Today, we "only" know to 50 billion decimal places Note 1 khet is 100 cubits, and 1 meter is about 2 cubits. A setat is a measurement of area equal to what we would call a square khet. An alternate conjecture exhibiting the value of is that the egyptians easily observed that the area of a square 8 units on a side can be reformed to nearly yield a circle of diameter 9. Rhind papyrus Problem 50 . A circular field has diameter 9 khet. What is its area. The written solution says, subtract 1/9 of of the diameter which leaves 8 khet. The area is 8 multiplied by 8, or 64 setat. Now it would seem something is missing unless we make use of modern data: The area of a circle of diameter
