Hi everybody.
00:02
We're going to be taking a look at this diagram on the left.
00:05
Here we have lines a and b cut by a transversal here and we have two angles that are indicated as angle one and angle two and somebody looked at angles one and angle two and they came to the conclusion that a must be parallel to b.
00:26
So in order to figure out if they were right or wrong, let's go ahead and come up with an example.
00:31
So our first step is is to come up with an example.
00:38
And i'm not given any information about angle one or angle two.
00:42
So i get to say whatever i want, i want for angle one.
00:46
So my measure of angle one, let's say 50.
00:49
And let's say the measure of angle to, let's say, 90.
00:56
Okay.
00:58
And i seem to be allowed to do that.
01:00
There is no sort of indication of what these numbers should be.
01:02
So i'm going to go ahead and plug these numbers in...
