A segment or curve cannot start and then start again without having stopped!
a point at each side
a ray continues on and on but a line segment stops
No. A line continues forever in both directions. A line segment stops.
Your probably spotting
Yes, a switch is a device that stops and starts current flow in a circuit.
The starter.
A line segment.
a polygon is any nth sided figure closed at all points a line segment is a line that stops at each end
Motion which starts and stops regularly.
The toe region of a curve represents the initial low-velocity, elastic deformation phase where stress and strain are directly proportional. It is the beginning segment of the stress-strain curve when a material starts to deform under load but before significant plastic deformation occurs. The toe region is where the material's structure begins to reorganize and align, allowing for further plastic deformation.
The letter is a capital U
I googled and found... Leg/Segment A leg is that portion of the trip between consecutive flight stops. The segment can be a group of legs, because the segment is that portion of a trip from boarding point to a deplaning point.
