For any triple of points P, Q and R in the plane, (not collinear), you can determine whether the angle P-Q-R makes a counterclockwise or a clockwise turn by looking at the sign of the quantity: where P [0] and P [1] refer to the x- and y-coordinates of P respectively, and similarly for Q and R.

Rewrite each of the axioms of the four-point geometry interchanging the words point and line (and making appropriate adjustments in the grammar and definitions).20 Each of these new axioms is called a plane dual, and the ... WebbOn the previous page we saw that, in a plane, expressions that involve points and lines can be rewritten in a way that points and lines are interchanged, for instance:. Two lines define (meet at) a point. Two points define (joint to make) a line. This can also apply to certain finite subsets of a plane, for example the fano plane, this consists only 7 points and 7 …

WebbDual Axiom 3. Not all lines meet at the same point. Dual Axiom 4. Any two distinct lines will intersect at exactly one point. Dual Axiom 5. For any two distinct points, there is at least one line that is on both of them. We can readily prove the dual axioms as theorems in Fano geometry, and conversely, Fano’s axioms are theorems in the dual ... WebbWe study Euclidean geometry to understand the fundamentals of geometry. Euclidean Geometry refers to the study of plane and solid figures on the basis of axioms (a statement or proposition) and theorems.
