A Video About Graphing a Perpendicular Line

 

Here is a video to help with parallel lines perpendicular lines.

Here's a good video about how to find parallel and perpendicular lines.



Here is a good video summarizing the type of angles formed when a transversal cuts a pair of parallel lines. For Sunday, I will post a video based more on the review packet that we didn't review well enough in class as I would have like to.

This video can help you make draw perpendicular lines. Just remember to find the slope of the first line using two points.

For example, (1,2) and (3,7). The slope of the line is (5/2) because, 7 - 2 = 5 and 3 - 1 = 2. Here's a video for perpendicular lines:


For parallel lines, know the slope of the original. Use the third point with the new slope. I will post something about this on Sunday.
