Lines m and n are parallel. use the diagram to identify the type of angle pairs. corresponding, alt. int. angle. alt ext. vertical, linear pair or consecutive interior angles

Angle 2 and Angle 7: Alt. Interior, Congruent

Angle 1 and Angle 5: Corresponding, Congruent

Angle 4 and Angle 7: Consecutive Interior, Congruent

Angle 5 and Angle 8: Vertical, Congruent

Angle 1 and Angle 2: Linear Pair, Supplementary

Angles                     Type                                                 Relationship

∠2 and ∠7                Alternative interior                             Congruent

∠1 and ∠5                 Corresponding angles                      Congruent

∠4 and ∠7                Consecutive interior angles              Supplementary

∠5 and ∠8                Vertical angles                                   Congruent

∠1  and ∠2                 Linear pair                                          Supplementary

Step-by-step explanation:

The lines m and n are parallel. The parallel line cuts by a transversal.

The following properties are holds true.

1) Corresponding angles are equal

2) Alternative interior angles are equal.

3) Linear pairs add upto 180 degrees.

4) Vertical opposite angles are equal.
