CARNOT, Géométrie de position , 1803

First edition.
Book in which Lazare Carnot exposes three theorems which will retain his name:
- Carnot's Japanese Theorem relating to an algebraic equality of distances in a construction using the inscribed circle and the circle circumscribed to a triangle
- Carnot's Theorem which gives a condition necessary and sufficient for three straight lines perpendicular to the (extended) sides of a triangle to be concurrent. This theorem can be considered as a generalization of the Pythagorean theorem.
- Carnot's theorem which relates to a condition so that points located on the sides of a triangle are located on the same conic.
