I recently completed my master's thesis on Desargues' Triangle Theorem under the direction of Dr. Elena Anne Marchisotto at California State University, Northridge. Thesis dedications and special thanks Girard Desargues AN EXPLORATION OF DESARGUES’ TRIANGLE THEOREM Introduction The triangle theorem of Girard Desargues (1591-1661) is the focal point for this thesis. We begin with a history of its creator and his work, briefly tracing the development of the branch of mathematics where it resides: projective geometry. Our examination of the triangle theorem will involve interpretation and analysis of Desargues’ original proof. Next we trace the evolution of different proofs of the theorem constructed by noted geometers of the nineteenth and twentieth centuries. We analyze these proofs in comparison to one another and to Desargues’ original demonstration.

30. Desargues' Theorem desargues theorem. In projective geometry, desargues theorem, namedin honor of girard desargues, states In a projective space http://www.fact-index.com/d/de/desargues__theorem.html

Main Page See live article Alphabetical index Desargues' theorem In projective geometry Desargues' theorem , named in honor of Girard Desargues , states: In a projective space , two triangles are in perspective axially if and only if they are in perspective centrally To understand this, denote the three vertices of one triangle by (lower-case) a b , and c , and those of the other by (captial) A B , and C . Axial perspectivity is the condition satisfied iff the point of intersection of ab with AB , and that of intersection of ac with AC , and that of intersection of bc with BC , are collinear, on a line called the axis of perspectivity . Central perspectivity is the condition satisfied iff the three lines Aa Bb , and Cc are concurrent, at a point called the center of perspectivity In an affine space nothing similar is true unless one lists various exceptions involving accidentally parallel lines. Desargues' theorem is therefore one of the most basic of simple and intuitive geometric theorems whose natural home is in projective rather than affine space. The truth of Desargues' theorem in the plane is most readily deduced by getting it as a corollary to its truth in 3-space. Two triangles cannot be in perspective unless they fit into a space of dimension 3 or less; thus in higher dimensions the span of the two triangles is always a subspace of dimension no higher than 3.

For Age: 4 years and up LeapPad by LeapFrog At Amazon on 4-15-2003. More Info This talking book comes with an interactive ''magic pen'' that works like a hand-held computer mouse pointer. Children can opt to turn the paper pages and listen to the story read with different voices for each character. Or they can interrupt the read-aloud session to play with the magic pen (permanently attached with a wire). They can point the pen tip to any word on a page and hear it pronounced, or touch a picture and hear a sound effect (such as ''Strike one!'' for the baseball bat). Very similar to the popular Living Books computer games, this 10-by-11-inch book is more portable than a home computer. Stories in this set include Lil's Loose Tooth, Richard Scarry's Best Word Book Ever, and Winnie the Pooh in A Sweet Good Morning.
