For line segment keep the hands in a fist and put their arms out like airplane wings to make a line segment with two end points. For the line keep the arms out, but put out the fingers (i like to call them party fingers) these are the arrows that represent the line going on and on, and on, and on...ok. For the ray...bring in one arm to the chest and make the hand a fist. The other hand stays open (party fingers) and out (one winged plane). You can do the hand motions for acute, and obtuse angles by over exaggerating the names....an a "cute" angle pinches the cheeks of a baby and is said in a very petite voice...an obtuse angle is said in a very deep voice and the arms spread out like a budding flower. Right angle...well; put one arm with the fingertips of the hand touching the elbow of the other arm that is pointing to the ceiling. Perpendicular, parallel and intersecting lines can all be done by crossing the arms (or not)....I am much better at doing these than explaining these...hope this helps.
