This document discusses closed and open curves. A closed curve is a shape where the line meets back at the starting point without lifting the pencil, forming a complete loop. An open curve is a shape where the line does not meet back at the starting point and is not a complete loop. Students are asked to identify figures as either closed or open curves.
