Question

if two lines are parallel then would the co-interior angles be complementary​

Answer 1

Answer:

Angles Made by a Transversal to Two Parallel Lines

Angles Made by a Transversal to Two Parallel LinesEach pair of corresponding angles is equal in measure. Each pair of alternate interior angles is equal in measure. Also, each pair of interior angles on the same side of the transversal are supplementary, i.e., co-interior angles are supplementary.

Answer 2

Angles Made by a Transversal to Two Parallel Lines

Each pair of corresponding angles is equal in measure. Each pair of alternate interior angles is equal in measure. Also, each pair of interior angles on the same side of the transversal are supplementary, i.e., co-interior angles are supplementary.
