*By definition, to construct a 180 degree angle is to draw a straight line. Also, because it has an infinitely small measure, it is impossible to construct it- the only way to make one is to draw a straight line and put a vertex on it. You could also draw a ray. Of course, a zero-degree angle is a line, so it is sometimes not even considered an angle. Use this at your own discretion.
