Menelaus and Ceva Menelaus of Alexandria (circa 100 AD) was among the first to clearly recognize geodesics on a curved surface as the natural analogs of straight lines on a flat plane.  Earlier mathematicians had considered figures on a spherical surface, but it was Menelaus who had the insight to construct a complete geometry of the sphere with great circle arcs taking the place of line segments.  For example, he defined "spherical triangles" as figures comprised of three great circle arcs, and developed a family of trigonometric relations for such figures.  The most famous of these is still known as Menelaus' Theorem, although it's commonly presented only in the planar version (which was probably known to Euclid ).  In this form the theorem gives the necessary and sufficient condition for three points on the extended edges of a plane triangle to be co-linear.  Consider the triangle shown below Letting [xy] denote the distance between points x and y, the Theorem of Menelaus states that the points a,b,c located on the (extended) edges BC, AC, AB of a triangle ABC are colinear if and only if To prove this, consider a rectangular coordinate system xy with respect to which the coordinates of the vertices A,B, and C are (0,0), (

Return to Math Index Page Heron, Pythagoras, Euler, Ptolemy and Ceva: Some Contributions to Euclidean Geometry Stanley Wong The Academic Setting This unit will be used at Del Norte High School in Albuquerque, New Mexico. It is designed with my Honors Geometry class in mind. Students can be freshman or sophomores. The freshman are recommended by their eighth grade Algebra I teachers if they have exhibited a strong aptitude for mathematics. Math teachers from our feeder schools (Cleveland and McKinley Middle Schools) have been briefed on these recommendations. The sophomores are those who have successfully completed Honors Algebra I as freshman or who have shown great promise in regular Algebra I and who have been recommended by their teacher. Students in Honors Geometry will study, in greater depth, the concepts, techniques, and theory of the regular geometry course. Both acceleration and enrichment are integral components of the curriculum. This is the second course in the Honors/Advanced Placement Program in Mathematics and students will earn a weighted grade in this course. (Albuquerque Public Schools 16.0)

The whole world reestablished this book starting with the Islamic translation on through time. THALES, FOUNDER OF GREEK GEOMETRY (585 B.C.E.) The birth of Greek astronomy has been attributed to Thales of Miletus. Thales brought from Egypt a number of fundamental geometric principles. Thales, an Ionian (western border of Asia Minor) who was active near the start of the sixth century bc has been credited with a number of geometric theorems. 1. A Circle is bisected by its diameter. 2. Angles at the base of any isosceles triangle are equal. 3. If two straight lines intersect the opposite angles formed are equal. 4. If two triangles have two angles and one side respectively equal, the triangles are equal in all respects. Thales was also well known for forecasting the solar eclipse, so he was also considered a scientist.

74. An Alternative Introduction To Proof In Dynamic Geometry - Association Of Teache This interesting result is called ceva s Theorem after an Italian mathematiciannamed giovanni ceva who published it in 1678. http://www.atm.org.uk/journals/micromath/articles/geometry/proof/introduction.ht

An Alternative Introduction to Proof in Dynamic Geometry The recent development of powerful new technologies such as and The Geometer's Sketchpad with drag capability has made possible the continuous variation of geometric configurations and allows one to quickly and easily investigate whether particular conjectures are true or not. What are the implications of the development of this new software for the teaching of proof? How can we still make proof meaningful to children? Although several useful activities with Cabri were demonstrated in the Summer 1992 issue of MicroMath , these particular questions were unfortunately not addressed there. Traditionally, the typical approach to geometry is to try and create doubts in the minds of pupils about the validity of their empirical observations, and thereby attempting to motivate a need for deductive proof. From my experience, the strategy of raising doubts in order to create a need for proof is often not successful when a geometric conjecture has already been thoroughly investigated through continuous variation with dynamic software like Cabri or Sketchpad. When pupils are able to produce numerous corresponding configurations quickly and easily, they have little need for further conviction or verification. The problem is further intensified by a facility on
