Constructing Parallel Lines (using a straightedge and compass)
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.Music by longzijun, http://longzijun.wordpress.com/ .My math materials in English: http://www.antonija-horvatek.from.hr/... .My (whole) website: http://www.antonija-horvatek.from.hr/ .
