Did you know that we can draw parallel lines using just a straightedge and a compass (without a set square)? In that case, we say that we CONSTRUCT parallel lines. To learn how to do it, watch this video. 1st part of the video: For given line a, we construct line b which is parallel to the line a. 2nd part: For given line c and external point T, we construct line d which goes through point T and is parallel to line c. Constructing parallel lines on paper. Video without words. Thanks to Rex Boggs, Rockhampton Grammar School, Australia (http://bit.ly/rexboggs ) for help with the English translation.
