We want to determine in this question which type of lines are not represented.
00:11
When i have this type of question, usually i remember it's a not question.
00:15
So i try to go down here and do a quick true or false that sometimes helps me as a strategy.
00:20
So, you know, are parallel lines represented true or false? these marks right here show that the lines are parallel.
00:32
So parallel lines, it's true there in the diagram.
00:37
Perpendicular lines are shown by right angles, angles that cross the 90 degree angle.
00:42
Because we see those two 90 degree angles there, it's true that perpendicular lines are represented.

I'm going to jump to intersecting, so that's a really, really basic definition and concept...
