Answer:

Theorem:

If ABC is a triangle then <)ABC + <)BCA + <)CAB = 180 degrees.

Proof:

Draw line a through points A and B. Draw line b through point C and parallel to line a.

Diagram included :

Since lines a and b are parallel, <)BAC = <)B'CA and <)ABC = <)BCA'.

It is obvious that <)B'CA + <)ACB + <)BCA' = 180 degrees.

Thus <)ABC + <)BCA + <)CAB = 180 degrees.
