So you want to mark four points.
00:02
F, e, f, g, and h, such that no three of them are collinear.
00:08
So let's say i mark them like so.
00:12
So here's e, f, g, and h.
00:16
And now it says, draw lines through, taking two at a time, and how many lines can you draw? and if we counted them, we can draw one.
00:27
Now let me get to another color.
00:31
That didn't change.
00:33
Let me try again.
00:35
I think that changed.
00:37
One, two, three, and then four, five, and six.
00:46
So there are six lines that we could draw, and the lines could continue to go through those and extend on.
00:54
I just stopped in the segments.
00:56
That would also be found by taking a combination of there are four points, and you want to pick them in pairs and that will end up being six.
01:04
Now question two...
