two angles that sum 180 degrees.
What are supplementary angles?
x
What is 90 - x?
90 degrees
What is 90?
This relationship describes two congruent angles that are on the same side of the transversal and match up exactly by sliding one over the other without turning.
What are corresponding angles?
Find x.
A pair of vertical angles.
Angle 1 is 4x degrees, and Angle 2 is (5x - 30) degrees.
What is 30?
When a transversal intersects parallel lines, these congruent angles are formed.
Corresponding Angles
5x
What is 90 - 5x?
7x
What is 180 - 7x?
This relationship describes two congruent angles that are on the different sides of the transversal and match up exactly by turning one around over the other.
What are alternate interior or exterior angles?
Find the measure of angles 1 and 2.
