It is the additive property of equality, as the additive property of length, as applied to adjacent or parallel line segments.
They can not be line segments on the same line, but they can both be line segments.
sometimes parallel.
Lines
I
Two points of parallel segments are writing with two lines like the following. (e.g.. ) For example if points AB are parallel to GI then you would write it like this (e.g.. ABGI)
If 2 segments have the same length they are known as 'congruent segments' IE: segment AB=segment AC (or AB=AC) then AB @ AC (or AB is congruent to AC)
segments AB, CD, BD.
It is the additive property of equality, as the additive property of length, as applied to adjacent or parallel line segments.
They can not be line segments on the same line, but they can both be line segments.
sometimes parallel.
There is no specific name - other than what you used: "a pair of parallel line segments".
Letters that have parallel line segments are H, E, F, M, and N
how many pairs of parallel line segments does a stop sigh have
false
they are not parallel
If the lines AB and CD are parallel then they both will have the same slope of -8 but with different y intercepts
