Hello.
00:04
This is problem 11 in your geometry textbook.
00:11
This problem deals with collinearity of points and drawing a diagram to represent it correctly.
00:20
So in this problem, we are required to draw a diagram where f is between points a and e, and it's also between points s and r, and those four points a, e, r and those four points a, e, r and s are non -colonial.
00:39
Well, when i first read this problem, f is between a and e and f is between s and r.
00:50
So at first, i was thinking that i had some line, and f was here in the middle, and here i had my a and my e, and my s, and my r.
01:12
If i had this design, f is in between a and e.
01:17
F is also in between s and r, and that would satisfy it.
01:22
But part c tells us that the four points are not collinear.
01:26
So all four points cannot be on the same line.
01:30
Three of them, up to three, can be on the same line, but the fourth one cannot...
