and our goal is to construct another line

by creating what will eventually be a transversal

So I'm just drawing a line that goes through my point

Do that, so it's going to look like that.

And then, I'm really just going to use the idea

of corresponding angled congruents for parallel lines.

and think about this angle right over here.

And so where should the point be on this left end?

using my compass, so I'm adjusting it a little bit

to get the distance between those two points.

And then I can use that up over here to figure out,

I can figure out that point right over there.

And just like that, I now have two corresponding angles

to find my transversal and parallel lines,

and make it go through those points that I just created,

so let's see, make sure I'm going through,

and I have just constructed two parallel lines.

And once again, how do I know that this line

Because we have a transversal that intersects both of them

and these two angles, which are corresponding angles,
