What is the relation between the two straight lines?

00:00:07.620 --> 00:00:12.180
We notice almost immediately that these two lines intersect.

00:00:13.830 --> 00:00:16.390
That makes them intersecting lines.

00:00:18.030 --> 00:00:23.480
It also means they can not be parallel lines because they intersect.

00:00:25.970 --> 00:00:30.850
We can also say that these two lines are not perpendicular.

00:00:32.770 --> 00:00:38.420
What we did here is we drew a line that would be perpendicular to these lines.

00:00:40.600 --> 00:00:45.400
But we’ve been given no indication that these angles measure 90 degrees.

00:00:47.830 --> 00:00:50.580
So we can say that they’re not perpendicular.

00:00:50.850 --> 00:00:52.780
But they are intersecting.

00:00:53.220 --> 00:00:58.940
The relation between these two straight lines is intersecting but not perpendicular.
