Why do the angles in a triangle add to 180 degrees, but if you walk the lines of a triangle you would turn 360 degrees?

The difference is deflection angles and internal angles are not the same.

If you travel in a straight line for 1 meter, then deflect 60 degrees to the right, travel 1 meter, then deflect 60 more degrees to the right, travel one meter, you've constructed half of a hexagon.

In order to do a triangle, each deflection would be 180-60=120 degrees.
