Angle Pair Relationships Created by a Transversal and 2 parallel lines
Corresponding Angles
Alternate Exterior Angles
Consecutive Exterior Angles
Consecutive exterior angles are congruent.
If one angle is 30 degrees, its consecutive exterior angle pair would also be 30 degrees
If one angle is (2x-5) degrees and the other angle is 105 degrees. You can find the value of x and the missing value using the equation:
2x - 5 = 105
2x - 5 = 105
2x = 110
x = 55
Both angles equal 105 degrees.
2(55)-5 = 105
Both angles will be acute or both angles will be obtuse.
