Determine the missing reason in the fifth line of the following proof.
Lana71 [14]

Option D:

Converse of the corresponding angle postulate

Solution:

1. Given a || b.

2. <u>Alternate Interior angle theorem:</u>

If two parallel lines are cut by a transversal, then the alternate interior angles are congruent.

⇒ ∠1 ≅ ∠3

3. Given ∠2 ≅ ∠3

4. <u>Transitive property of equality:</u>

If a = b and b = c, then a = c.

So, from (2) and (3), we can say ∠1 ≅ ∠2.

5. ∠1 and ∠2 are corresponding angles.

<u>Converse of the corresponding angle postulate:</u>

If two lines are cut by a transversal and the corresponding angles are equal then the two lines are parallel.

⇒ c || d.

Option D is the correct answer.

Converse of the corresponding angle postulate.
