Use the alternate Interior Theorem diagram to answer the question. give the missing reason in this proof for the letter given.

Statements:
1. l || n
Reasons:
1. Given
2. Angle 2 = Angle 6 8. a. Corresponding angles
3. Angle 4 = Angle 2 9. b. Vertical Angles
4. Angle 6 = Angle = 4 10 c. (I only need help on this one does anyone know what it is

To determine the missing reason in the given proof, we need to look at the statements and identify the relationship between Angle 6 and Angle 4.

From Statement 3, we know that Angle 4 is congruent to Angle 2. And from Statement 2, we know that Angle 2 is congruent to Angle 6. Therefore, by the Transitive Property of Equality, we can conclude that Angle 6 is congruent to Angle 4.

Thus, the missing reason in this proof would be the Transitive Property of Equality.
