Extractions: Nadat hij de eerste paar jaar van zijn leven door een oom was opgevoed, ging Joseph naar school in Toul, waar hij met name les in klassieke talen kreeg. Vervolgens ging hij naar Parijs, om aan het lessen in wiskunde te krijgen. Al tijdens zijn schooltijd las hij het enige Franse wiskundetijdschrift van dat moment van Gergonne en naar aanleiding van een artikel over Euclidische meetkunde in dit blad, bedacht hij, slechts vijftien jaar oud, zelf enige stellingen. Hij stuurde deze ook op naar Gergonne, maar ze werden nooit gepubliceerd. De jonge Liouville had al jong besloten professioneel wiskundige te worden en hij deed dan ook toelatingsexamen voor de . Dit was eigenlijk een school die ingenieurs voor het leger opleidde, maar het wis- en natuurkundig niveau lag zo hoog dat het voor aanstaand wiskundigen welhaast verplicht was hier te studeren. Liouville slaagde voor toelatingsexamen en betrad in 1825 de school, waar op dat moment onder meer Cauchy les gaven. Van Cauchy kreeg Liouville geen les, maar omdat Cauchy op dat moment een van de belangrijkste Franse wiskundigen was, had hij zeker veel invloed op de jonge Liouville. Liouville was een goede leerling, zij het niet de beste van de school

Extractions: Recommend this site Giovanni Ceva (1648-1734) proved a theorem bearing his name that is seldom mentioned in Elementary Geometry courses. It's a regrettable fact because not only it unifies several other more fortunate statements but its proof is actually as simple as that of the less general theorems. Additionally, the general approach affords, as is often the case, rich grounds for further meaningful explorations. In a triangle ABC, three lines AD, BE and CF intersect at a single point K if and only if (The lines that meet at a point are said to be concurrent 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, AEG and BCE, AGK and BDK, CDK and AHK. From these and in that order we derive the following proportions: AF/FB=AH/BC (*) CE/EA=BC/AG (*) AG/BD=AK/DK AH/DC=AK/DK from the last two we conclude that AG/BD = AH/DC and, hence, BD/DC = AG/AH (*).

Extractions: The Gergonne Point, so named after the French mathematician Joseph Gergonne, is the point of concurrency which results from connecting the vertices of a triangle to the opposite points of tangency of the triangle's incircle. This essay will prove the existence of this point for any triangle, explore its relationship to the Euler line, if any exist, and discuss the possible usefulness of this point. Most geometry students are familiar with the several points of concurrency and the steps necessary to construct such points. These might include some of the following points of concurrency (click for a GSP sketch illustration): perpendicular bisector point of concurrency (circumcenter) angle bisector point of concurrency (incenter) median point of concurrency (centroid) altitude point of concurrency (orthocenter) An illustration of these below: A GSP sketch of the Gergonne Point is shown below.

Extractions: Essay 3: Gergonne Point by Anita Hoskins and Crystal Martin The Gergonne Point was discovered by and named after Joseph Diaz Gergonne . The theorem goes as follows: the segments from the vertices of a triangle to the points of tangency of the incircle with the opposite sides of the triangle are concurrent. This point of concurrency is called the Gergonne point. The proof can be done easily by using Ceva's Theorem Proof: See Figure 1 below. Let c1 be the incircle (green) of triangle ABC, and let point I be the center of c1, or incenter of the triangle. Recall that the incenter is the point of concurrency of the angle bisectors (red) of a triangle. Also, that the incircle is formed by constructing lines (blue) through point I perpendicular to the sides of the triangle. The points where these lines intersect the sides of the triangle (points F, D, and E) are the points of tangency of the incircle. Figure 1 Notice triangles AFI and AEI (figure 2). Angle AFI and AEI are both right angles, and angle FAI = angle EAI because of the angle bisector. Since angle AFI = angle AEI, and angle FAI = angle EAI, then angle FIA = angle EIA. The length of side AI = the length of side IA by the reflexive property. Therefore, triangle AFI is congruent to triangle AEI by angle-side-angle congruency. So, AF = AE. Figure 2 The same argument is used to prove that BF = BD, and CD = CE. See figure 3.
