Lines

straight lines / curved lines Is it going straight? rising curved line falling

straight lines / curved lines rising straight line rising falling curved line falling straight

straight lines / curved lines What is this? What is this?

concurrent straight lines passing through the same point Will these 3 lines pass through the same point? so they are concurrent lines

concurrent straight lines Are these lines concurrent? Which are concurrent now? Which are concurrent now?

collinear points Are these points on the same straight line? so they are collinear so they are not collinear

collinear points Which are collinear among these? Which else? Bottom 3? bottom 3 are not collinear

parallel straight lines went beyond top line went below top line touching both lines these lines are parallel to each other even now they are not parallel to each other
