This video describes the steps necessary to copy a line segment using a compass and straightedge. At the beginning of the video the presenter lists a couple of reasons for using this construction. The video is easy to follow.
This video demonstrates how to construct a line perpendicular to another line such that the constructed line goes through a point not on the original line. The video should be viewed after one understands how to construct a perpendicular bisector which is shown in another video in this collection.
This video illustrates the steps to follow in order to construct an angle bisector. The presenter does a good job of walking the viewer through this construction and making sure the copy is labeled correctly.
This video demonstrates the steps to follow in order to construct a perpendicular bisector using only a compass and straightedge. In the beginning of the video the presenter lists a couple of uses for this construction. The steps for this construction are presented clearly and the images are easy to follow.
