Współrzędne  zaznaczonych punktów są odległościami od odpowiednich osi układu współrzędnych. Odległość punktu od początku układu współrzędnych , można   obliczyć z twierdzenia Pitagorasa , jeśli  potraktujemy  jego współrzędne jako przyprostokątne w trójkącie prostokątnym , a szukaną odległość jako przeciwprostokątną. a) R=32+(−1)2=10<svg xmlns="http://www.w3.org/2000/svg" width='400em' height='1.08em' viewBox='0 0 400000 1080' preserveAspectRatio='xMinYMin slice'><path d='M95,702
