What type of angles are these? What do you know about their measures?
Alternate Interior Angles Congruent (same measure)
What type of angles are these? What do you know about their measures?
Alternate Exterior Angles Congruent (same measure)
What type of angles are these? What do you know about their measures?
Supplementary Angles which equal 180 degrees
What kind of angles are angle 1 and 2? What do you know about their measures?
m<a = 80 because the two angles are supplementary (they add to 180 degrees)
What is measure of angle a? How are these two angles related?
m<x = 80 because the angles are alternate exterior so they have the same measure
What is the measure of angle x? How are these two angles related?
m<x = 112 degrees because the two angles are corresponding so they have the same measure
What is the measure of angle x? How are these two angles related?
m<x = 118 degrees because the two angles are alternate interior so they have the same measure
What is the measure of angle x? How are these two angles related?
m<x = 110 degrees because they are corresponding angles so they have the same measure
What is the measure of angle x? How are these two angles related?
m<z = 122 because the two angles are consecutive (they add to 180 degrees)
What is the measure of angle z? How are these two angles related?
Angles that are on the same side of the transversal and in corresponding positions (same positions)
What is the definition of corresponding angles?
Angles that are on opposite sides of the transversal and inside the parallel lines
What is the definition of alternate interior angles?
Angles that are on opposite sides of the transversal and outside the parallel lines
What is the definition of altnernate exterior angles?
Angles that add to 90 degrees
What is the definition of complementary angles?
Angles that add to 180 degrees
What is the definition of supplementary angles?
Angles that are on the same side of the transversal and inside the parallel lines
What is the definition of consecutive angles?
Angles that are opposite of each other when two lines cross
What is the definition of vertical angles?
