Exploring Lines - Page 4 (6th grade, review for 7th grade)
Line property 4: if two lines are
parallel (notation: L1 || L2), then from a given point on
one line there exists a shortest line segment whose other endpoint lies on the
second line. The length of this line segment is the distance d
between L1 and L2. Since these are parallel lines this
distance does not vary along these lines. These segments are perpendiculars to
these lines (notation S ⊥ L1). The segment S is also said to be othogonal
to the parallel lines.
Another view is: given a line L and distance d,
there exists exactly two lines, one on each side of L, at the distance d
from L.
