Transversals

If mL1= 79, what is mL2 ? How do you know?

• mL2= 79 because alternate exterior angles are congruent

• mL2= 79 because vertical angles are always congruent

• mL2= 101 because linear pairs are supplementary

• mL2= 101 because it looks like it is 101 degrees in the diagram

If mL3= 97, what is mL6 and how do you know?

• mL6 is 97 because alternate interior angles are congruent if the lines are parallel

• mL6 is 97 because alternate interior angles are ALWAYS congruent if a transversal crosses any 2 lines

• mL6 is 83 because consecutive interior angles are supplementary

• mL6 is 83 because alternate interior angles are supplementary
