Final answer:
In the case where the 2 parallel lines are perpendicular to the transversal, all 8 angles will be the same degree measure of 90 degrees.
Step-by-step explanation:
In the case where the 2 parallel lines are perpendicular to the transversal, all 8 angles will be the same degree measure. This is because when two lines are perpendicular, they form right angles, which have a measure of 90 degrees. The transversal cuts through these right angles, creating congruent angles on both sides. Therefore, all 8 angles will have a measure of 90 degrees.
