Includes links to biographies of major contributors to geometry. Hidden Irrationals (English Version) (Spanish Version) What's the rule? Students will find line segments that they can and cannot draw of various irrational lengths, and then find the rule that allows them to draw or not draw. The page should be printed and the segments shaded in. Hidden Polygons Students learn to identify various polygons by locating them on triangular gridpaper. The page can be printed and the figures shaded in. Links to other polygon sites are included. Isosceles Triangle Puzzler Students use the Isosceles Triangle Theorem to analyze a problem with similar triangles. Answers can be submitted online. Impossible Triangles Students use several different rules to determine triangle "impossibilities". Answers can be checked online. ... graded online. The Golden Ratio This lesson introduces the golden ratio with a measuring activity. Students will also build a rectangle that approaches the golden ratio.

25. 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

35. The Geometry Applet This geometry applet is being used to illustrate Euclid s Elements. Above you see an icosahedron, that is, a regular 20sided solid, constructed according http://aleph0.clarku.edu/~djoyce/java/Geometry/Geometry.html

The Geometry Applet version 2.2 *** If you can read this, you're only seeing an image, not the real java applet! *** I began writing this applet in Feb. 1996. The current verion is 2.2 which fixes a couple of bugs in 2.0 and has a new construction to find harmonic conjugate points. Version 2.0 (May, 1997) does three-dimensional constructions whereas the earlier version 1.3 only did plane constructions. Version 2.0 also has many minor improvements. It takes a while to test everything. Please send a note if you find any bugs. They'll be fixed as soon as possible. (Note that arcs and sectors on slanted planes cannot yet be illustrated.) Also, there may be still later versions than 2.2 with more functionality. This geometry applet is being used to illustrate Euclid's Elements . Above you see an icosahedron, that is, a regular 20-sided solid, constructed according to Euclid's construction in proposition XIII.16 Another example using this Geometry Applet illustrates the Euler line of a triangle Here's how you can manipulate the figure that appears above. If you click on a point in the figure, you can usually move it in some way. A free point , usually colored red, can be freely dragged about, and as they move, the rest of the diagram (except the other free points) will adjust appropriately. A sliding point

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
