HW#6 p. 149: 18-25

Recall: A transversal is a line that cuts across two other lines.  (think transcontinental- across continents)

Remember terms that go together.  Transversals have two sides, and a pair of angles can either be on the same side of the transversal or alternate sides of the transversal.  The two lines (that are not the transversal) in a diagram have an interior and an exterior, and each angle is going to be described by one of those words.

The trick to these problems is to identify the transversal.  The transversal for two given angles is the only line that is actually touching both angles.  Once you know that, you can label the other lines as “the other two lines.”  You now just combine vocab words.

If both angles are on the same side of the transversal and both angles are in the interior of the other two lines, then the angle pair is called “Same Side Interior Angles.”

Remember that Corresponding Angles are the special angle pair that satisfy these 3 conditions:

  1. They are nonadjacent
  2. They are on the same side of the transversal
  3. One angle is interior and the other is exterior.

Corresponding Angles has a better ring to it than “Same Side Nonadjacent Interior Exterior Angles…”
