NOW let's watch the second pair!
QUESTION: What can you conclude about perpendicular lines that are drawn in the coordinate plane? (Assume the lines are not aligned horizontally and vertically).
NOW let's do some pencil pushing!
That's all for now, folks!
Next time, we'll look at more pairs of lines. So what's your biggest takeaway for this lesson?
