A triangle has three points on it, and the sum of the exterior angles will always be greater than 180 degrees.
As a simple test, draw three dots in a triangle form, and join them up. Using a protractor, add the angles. This will be more 190degrees.
If you now place three dots in a straight line labelling them dots a, b, and c, and now join them up. The angle from the line between dots a-b, to the line between dots b-3 is 180degrees.
