Kassidy wants to prove that the interior angles of any triangle sum to 180°. she draws a line through one vertex parallel to the opposite side, and then she labels all the angles formed. drag a reason to match each statement in kassidy's two-column proof in the table below.

1.A straight line measures 180 degrees

2.Alternate interior angles theorem

Step-by-step explanation:

We have to prove that

Sum of interior angles of any triangle =180 degrees

Proof:

1.

Reason: A straight line measures 180 degrees

2.

Reason:Alternate interior angles theorem

3.

Reason: by definition of congruent angles.

4.

Reason: By substitution

Hence, proved.
