Yes, the lines are parallel since the slopes are the
same.

No, the lines are not parallel since the slopes are
not the same.
40.
When he measures the angle that each picket
makes with the 2 by 4, he is measuring
corresponding angles. When all of the
corresponding angles are congruent, the pickets
must be parallel.
41.
The 10yard lines will be parallel because they
are all perpendicular to the sideline and two or
more lines perpendicular to the same line are
parallel.
42.
Consecutive angles are supplementary; opposite
angles are congruent; the sum of the measures of
the angles is 360.
