Question 5

Use the drop-down menus to complete the proof.

Revolt · Accepted Answer

Use the drop-down menus to complete the paragraph proof showing that alternate interior angles are congruent. We know that lines a and b are parallel and that line c is a transversal because that is g: vertical; Use the drop-down menus to complete the paragraph proof showing that alternate interior angles are congruent. We know that lines a and b are parallel and that line c is a transversal because that is g: corresponding; Use the drop-down menus to complete the paragraph proof showing that alternate interior angles are congruent.

Question 10

Use the drop-down menus to complete the proof.

Revolt · Accepted Answer

✔ corresponding angles theorem; Given that w ∥ x and y is a transversal, we know that ∠1 ≅∠5 by the . Therefore, m∠1 = m ∠5 by the definition of congruent. We also know that, by definition, ∠3 and ∠1 are a linear pair so they are su: corresponding angles theorem; Given that w ∥ x and y is a transversal, we know that ∠1 ≅∠5 by the . Therefore, m∠1 = m ∠5 by the definition of congruent. We also know that, by definition, ∠3 and ∠1 are a linear pair so they are su: linear pair postulate; Given that w ∥ x and y is a transversal, we know that ∠1 ≅∠5 by the . Therefore, m∠1 = m ∠5 by the definition of congruent. We also know that, by definition, ∠3 and ∠1 are a linear pair so they are su: definition of supplementary angles
