So we see with this problem here, we have two vertices of an equal lateral triangle.
00:06
They're given to us as 7 .1, so 7 units to the right, 1 unit up.
00:10
And 2 1, 2 units to the right 1 unit up.
00:14
We want to figure out where the vertex will go.
00:19
The third vertex, we're going to put it.
00:24
It actually doesn't matter where we put it.
00:25
First thing we want to recognize, though, is that this is a distance of 5.
00:30
So we want to make sure that regardless of where we put it, it's also going to be a distance of five.
00:36
We know that it's going to be located in between these two.
00:40
So if it's in between these two, it's going to be at five.
00:45
So we know that our x value is five and our y value, let's say, is three...
