Step-by-step explanation:

Draw line a through points A and B. Draw line b through point C and parallel to line a. Since lines a and b are parallel, <)BAC = <)B'CA and <)ABC = <)BCA'. It is obvious that <)B'CA + <)ACB + <)BCA' = 180 degrees.....

First we will draw a line parallel to BC that is DE.

Then angle G is equals to angle C and angle F equals to angle B.

Then, angle a + angle b + angle c equals to 180 degree as angles on a straight line make up to 180.
