welcome what I want to do is show you

how to determine if points are collinear

or not now remember the definition of

collinear is points that are going to

lie on the same line so what we want to

pretty much do is look at points that

are on a line and we could say that

points D B and E are all collinear they

all lie in the same line as well as we

can look at the other line and say

points a B and C are also collinear now

the only point that is collinear for

both lines is point B because it's at

the intersection and it is on both lines

however we cannot say you know a and a

those are being non collinear lines

because they do not lie on the same line

same thing like C and D C and E or an D

so again for them to be collinear they

have to lie on the same line so those

are two examples of points that are all

going to be collinear thanks
