Howard draws a transversal, t, on two parallel lines AB and CD, as shown below.

Two parallel lines are shown cut by a transversal labeled t. 1, 2, 7 and 8 are marked clockwise as exterior angles. 4, 3, 6, and 5 are marked clockwise as interior angles

He makes the following table to prove that the alternate interior angles are equal.

Statement Justification
angle 2 = angle 6 Corresponding angles of parallel lines are congruent.
angle 2 = angle 4 Vertical angles are congruent.
angle 4 = angle 6 ?

Which is the missing justification?

Corresponding angles formed by a transversal

It is the 3rd choice, transitive propert.

Transitive property says that if a = b and b = c, then a = c.

Thats whats happening in this proof.
