5.4 – Parallel Lines and Transversals
Parallel Lines: recall: ______________________________________________
________________________________________________________________
When two parallel lines are intersected by a transversal (t) certain relationships
between the angles and their measures result.
Vertically opposite angles: angles are _______. “X”
2 =
3,
__ =
__,
__ =
__,
__ =
__
Corresponding angles: angles are _______. “F”
1 =
5,
__ =
__,
__ =
__,
__ =
__
Alternate interior angles: are _______. Angles on inside of
“Z”.
3 =
6,
__ =
__
Alternate exterior angles: are ________. Angles on outside of “Z”.
2 =
7,
__ =
__
Interior angles on same side of transversal: are
____________________ (add to 180º). Angles inside of “C”.
3 +
5 = 180º,
__ +
__ = 180º
Exterior angles on the same side of the transversal: are
___________________ (add to 180º). Angles outside of “C”.
1 +
7 = 180º,
__ +
__ = 180º
Note: another useful known supplementary angle is “angles on
a line add to 180º (
1 +
2 = 180º)
