Okay, so we have a segment that starts with point x1 y1 and ends with point x2y2 and we want to divide it into four equal parts.
00:12
So i'm just going to roughly estimate, let's say that this is the midpoint right here.
00:16
So i'm going to say that that part, that point, well, we'll find the coordinates of that point in a second.
00:22
And then we want to find this one over here and this one over here.
00:26
So how about if i call this one in the middle, x sub m, y sub m.
00:30
And then how about if i call the one over here on the left, x sub three, y, sub three, and the one on the right, x sub four, y, sub four, just so we can refer to them as something.
00:42
All right, let's start by finding x sub m, y sub m.
00:47
That's just your typical midpoint that you're going to get by averaging the x coordinates, x1 and x2, and averaging the y coordinates y1 and y2.
01:00
So that one is done.
01:05
Now let's move on to...
