Vocabulary
Any line that intersects two or more parallel lines.
What is a transversal
If two parallel lines are cut by a transversal, these angles are on the inside of the two parallel lines and on the same side of the transversal.
What are Same Side Interior Angles
Two angles are congruent. The measure of the first angles is 42 degrees, what is the measure of the second angle
What is 42
If a pair of adjacent angles formed by intersecting line are linear pairs, what is their relationship
What is supplementary
Two angles whose measures add up to 90o
What are Complementary Angles.
What is the relationship between angles 4 and 5?
What are Alternate Interior Angles.
One way to prove that lines are parallel lines is through understanding that corresponding angles are
What is congruent
Alternate exterior angles are found where relative to parallel lines and the transversal?
Outside of the parallel lines and on opposite sides of the transversal.
Angles that are found in the same position in a group of angles created by parallel lines and a transversal.
What are Corresponding Angles.
