A Matter of Appreciation
October 1999 I have a recollection. Years ago, a childhood friend of mine, Boris, shared with me with excitement an unusual experience he had on a visit to the Tretj'yakov Art Gallery in Moscow. He was accompanied by a professional painter, a good acquaintance of his older sister. While Boris was making a round in one of the halls, he observed that the painter remained all that time on the same spot studying a certain picture. Curious, my friend asked the painter what was it about the picture that kept him interested in it for so long. According to Boris, the painter did not reply directly, but, instead, stepped over to the picture and covered a spot on the picture with a palm of his hand. "Have a look at the picture and think of what you see," he requested. After a while, he uncovered the spot, stepped back and asked Boris to have another look. Well, almost 4 decades later, with the names of the painter and the picture long forgotten, I still vividly remember Boris' excitement when he told me of how entirely different, deeper and more beautiful, the picture appeared to him then. This recollection is haunting me. In retrospect, I regret to have never arranged with Boris to visit the gallery and learn how to really

http://www.mathpages.com/rr/s3-09/3-09.htm
3.9 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), (

Let American Consumer Counseling Help you Get Out of Debt!
Introduction Proof of Menelaus Theorem Diagram 1 In this instance, triangle ABC is cut by transversal LN, and the three segments having no common end are NC, MA, and BL. The three other segments are AN, BM, and FL. Since their products are equal, it is easy to conclude that if the product of one of the two groups of three segments becomes the numerator in a fraction with the other product as the denominator, the fraction would be equal to 1, hence the equation in the above figure. There is more than one proof of Menelaus, but the more elegant proof is the one that will be discussed in this paper. To start with, have any triangle ABC cut by transversal LN. (Refer to diagram 1) Extend BC such that it intersects with L and label the other two points of intersection M (on segment BA) and N (on segment CA.) After that, construct perpendicular segments p (A to MN), q (C to LN), and r (B to LM.) (Diagram 2) Diagram 2 It can be concluded: Therefore: 1) Triangle XMB := Triangle YMA. (AA Theorem)

Ceva's Theorem
This theorem was proved by Giovanni Ceva (1648-1734). Ceva's theorem states that given three arbitrary cevians AD, BE and CF, the three of them all meet at a point P if and only if (1) AF/FB · BD/DC · CE/EA = 1 (The lines that meet at a point are said to be concurrent
Proof:
Extend the lines BE and CF beyond the triangle until they meet GH, the line through A parallel to BC. There are several pairs of similar triangles: AHF and BCF, AGE and CBE, AGP and DBP, DCP and AHP. From these and in that order we derive the following proportions: AF/FB=AH/BC (*)
CE/EA=BC/AG (*)
AG/BD=AP/DP
AH/DC=AP/DP from the last two we conclude that AG/BD = AH/DC and, hence, BD/DC = AG/AH (*). Multiplying the identities marked with (*) we get AF/FB · BD/DC · CE/EA = AH/BC · BC/AG · AG/AH = (AH·BC·AG)/(BC·AG·AH) = 1 Indeed, assume that P is the point of intersection of BE and CF and draw the line AP until its intersection with BC at a point D'. Then, from the just proven part of the theorem it follows that AF/FB · BD'/D'C · CE/EA = 1 On the other hand, it's given that

Ceva's Theorem
Date: 03/04/99 at 21:41:16 From: Mark Ride Subject: Ceva's Theorem Hi, I am a grade 12 student and I can't seem to get a good solution for the following questions: (a) Ceva's Theorem" The three lines drawn from the vertices A, B, and C of triangle ABC, meeting the opposite sides in points D, E, and F respectively, are concurrent if and only if AF/FB*BD/DC*CD/EA = 1. This theorem is credited to seventeenth-century Itailian mathematician Giovanni Ceva. Prove it using vector methods. (b) The importance of Ceva's Theorem lies in its use to prove many classic results in geometry. Use Ceva's Theorem to prove each of the following results: (i) The medians of any triangle are concurrent. (ii) The altitudes of any triangle are concurrent. (iii) The interior angle bisectors of a triangle are concurrent. Date: 05/09/99 at 08:36:38 From: Doctor Floor Subject: Re: Ceva's Theorem Hi Mark, Thanks for your question. Let's consider Ceva's theorem: This theorem is about a triangle ABC, and points A' on sideline BC, B' on AC and C' on AB.
