Parallel Line through a point

Basic Construction 6

Now we need to construct a line parallel to another line and we always do this through a point. Once we prove to ourselves how to do it one time, we can just recreate our steps using a new tool!

Tool Practice

Use the tools in the applet below to construct a parallel line to AB through C, there are actually multiple ways to do this! Remember that parallel lines are perpendicular to a third line, if you think back to our definitions of parallel. See what you can figure out on your own but if you need help watch the video below for help.
