Two parallel lines are intersected by a third line so that angles 1 and 5 are congruent. which statement is true about angles 3 and 5? they are acute. they are congruent. they are complementary. they are supplementary.

Angle 1 and angle 5 are congruent. Angle 1 and angle 3 form a straigt-line angle, which add up to 180°. Thus angle 1 and angle 3 are called supplementary angles. Because angle 1 are congruent to angle 5, that means angle 5 and angle 3 are also supplementary to each other.

They are supplementary
