7
Two or more angles whose measures add up to 90 degrees 30 x

8
Two or more angles whose measures add up to 180 degrees 120x

9
Opposite Angles formed when two lines intersect. They are always equal! 140

10
A line that intersects two or more parallel lines. Corresponding Angles are congruent.

38
Opposite Angles formed when two lines intersect. They are always equal! 140

39
Two interior angles on the opposite side of the transversal. They are always equal if the two lines are parallel.

40
