Question

Given a || b with transversal t, explain why ∠1 and ∠3 are supplementary.

Answer 1

Answer:

OPOSITE SIDES OF LINE t

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

∠1 and ∠2 are supplementary.

m∠1 + m∠2 = 180°

∠2 ≅ ∠ 3 (Alternate interior angles)

m∠1 + m∠3 = 180°

Thus, ∠1 and ∠3 are suplementary angles.
