Re: direction of line segmentsHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20131202 00:12:06
Re: direction of line segmentsyes, what i wanna do is.. if angel of segment ab is same as angle of bc Last edited by pari_alf (20131202 00:22:10) #4 20131202 05:39:58
Re: direction of line segmentshi pari_alf But, if all you want is to see if the points are colinear, you could just work out the gradient of AB and the gradient of BC, to see if they are the same.
