ETYMOLOGIA SŁOWA DIAMETER
From Medieval Latin diametrus, variant of Latin diametros, from Greek: diameter, diagonal, from dia- + metron measure.
CO OZNACZA SŁOWO DIAMETER
Średnica
W geometrii średnica okręgu to dowolny odcinek linii prostej, który przechodzi przez środek okręgu i którego punkty końcowe leżą na kole. Może być również definiowany jako najdłuższy akord koła. Obie definicje są również ważne dla średnicy kuli. Słowo "średnica" pochodzi od greckiego διάμετρος, "średnicy okręgu", od δια- "przez, przez" + μέτρον, "środek". Często jest to skrót DIA, dia, d lub ⌀. W bardziej nowoczesnym zastosowaniu długość średnicy nazywa się również średnicą. W tym sensie mowa o średnicy, a nie o średnicy, ponieważ wszystkie średnice okręgu lub kuli mają tę samą długość, czyli dwa razy większy od promienia r. Dla wypukłego kształtu w płaszczyźnie, średnica jest określona jako największa odległość, którą można utworzyć pomiędzy dwiema przeciwległymi liniami stycznych do jej granic, a szerokość jest określona jako najmniejsza taka odległość. Obydwa wielkości można efektywnie wyliczyć przy użyciu obrotowych zacisków.
Definicja słowa diameter w słowniku
Pierwsza definicja średnicy w słowniku jest linią prostą łączącą środek figury geometrycznej, szczególnie okrąg lub kulę, z dwoma punktami na obwodzie lub powierzchni. Inną definicją średnicy jest długość takiej linii. Średnica to także grubość czegoś, zwłaszcza o okrągłym przekroju.
