Determine which of the following lines is parallel to line . You may use any method you choose - be ready to explain
it to the class! After you make your selections, jot down some notes about what it means for two lines to be
parallel.
Does your meaning of “parallel lines” still hold in three dimensional space? Explain your thinking using a drawing
or a physical model.
In each of the three examples below, you are given one pair of lines that appear to be parallel, and a transversal to those lines. Which of the pairs of lines are actually parallel? Justify your answer in at least two ways.
The figure below shows two parallel lines and a transversal. All of the angles are labeled with letters starting with
in the upper left hand corner, then moving in alphabetical order counter clockwise around the upper intersection
and then the lower intersection.
