Question

Which lines are parallel? Justify your answer.

Lines a and b are parallel because their alternate exterior angles are congruent.
Lines a and b are parallel because their same side exterior angles are supplementary.
Lines e and f are parallel because their alternate exterior angles are congruent.
Lines e and f are parallel because their same side exterior angles are congruent.

Answer 1

Answer:I pretty sure it's the ones gong left to right which is e and f

Explanation:

Answer 2

Option D is correct. Line e and f are parallel because their same side exterior angles are congruent.

Based on geometry, the line a and b are not parallel. This is so because their same side exterior angles are not supplementary.

• Supplementary angles sum up to 180
• From the diagram, 75 + 115 = 190 degrees (showing that they are not supplementary)

Line e and f are parallel because their same side exterior angles are congruent.
