projective duality between pole and polar

Summary[edit]

Description
Italiano: Nel piano resta dato un principio di trasformazione col quale si dimostra il principio di Dualità tra polo e polare, quando sia data una conica delta ed un punto P. Ogni punto P del piano ha la sua retta polare p„ e quando un punto M percorre la retta p,, la retta polare di M ruota intorno al polo P della retta p.
