NettetParallel Lines, and Pairs of Angles Parallel Lines Lines are parallel if they are always the same distance apart (called "equidistant"), and will never meet. Just remember: Always the same distance apart and never touching. The red line is parallel to the blue line in each of these examples: Parallel lines also point in the same direction. NettetTheorem 1: If a line is drawn parallel to one side of a triangle to intersect the midpoints of the other two sides, then the two sides are divided in the same ratio. Suppose ABC is a triangle and DE is a line parallel to BC …
