C Country Boy Math Team Jan 2015 3,261 899 Alabama May 31, 2016 #2 What do you mean by "similar lines"? I could see saying that two line segments are "similar" if and only if they have the same length but that does not apply to lines. And, as for "angles delineated", what if the lines are parallel?
