So in this problem, what we want to do is use copies of the rectangles shown to show how we could either one tile the plane or how we could not tile the plane.
00:08
So let's start by tiling the plane.
00:10
So notice we have a two by three rectangle.
00:12
So let's see if we were to go across.
00:14
So it would be two by three.
00:15
So that would be one, number two by three, and number two by three.
00:20
And notice we would go across the whole thing.
00:22
So we could do this for each of our rows here.
00:24
We can go across again.
00:26
We'll add that last one at the end.
00:28
We'll go down two over three.
00:29
Down 2 over 3, down 2 over 3.
00:33
And notice, we're just going to keep repeating this pattern until we cover the whole thing.
00:43
There we go...
