Hi all,

[image: изображение.png]
Could someone explain to me how comparable distance works for point (P) and
segment (AB), is it always shorten distance to line (length of red
perpendicular from P on the pic above) or really to "limited" segment -
nearest point _ON_ it (length of PA for the pic above)?

Thanks in advanced for help!
