Author:Kaitlyn Bigos

Directions

Use the 3D figure below to determine whether the pairs of lines named in questions #1-6 are parallel, perpendicular, or skew. To help you visualize their relationship, you may want to use the line tool Toolbar Image to create a line on the two given points for each line. After creating your two lines, click Toolbar Image to allow you to move the figure around and get a better perspective of what is happening. Once you are done with each question, you can delete the lines you created and reset the figure by clicking on the circular arrows in the top right corner.
