Perpendicular lines

Please watch this video  and try this worksheet.  If you don't have a printer, then try to copy down your work.  I believe you have the first sheet, so try to finish that one and then try the second sheet.  I did attach the answer key as you can check your answers.  Please make a note at the point that you don't understand and we will work on that when you come back.  Email me how you are feeling and we will go from there.
