Angle Pair Relationships Created by a Transversal and 2 parallel lines

Alternate Interior Angles

Consecutive Interior Angles

Consecutive Exterior Angles

Both angles will be acute or both angles will be obtuse.

Consecutive exterior angles are congruent.

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

Both angles equal 105 degrees. 2(55)-5 = 105

2x - 5 = 105 2x = 110 x = 55

If one angle is 30 degrees, its consecutive exterior angle pair would also be 30 degrees
