line segments are lines that have two distinct endpoints (a dot) •
(see example 2)
finding them on a number line(example 3)
look for two dots
the line between them is the line segment
on a figure(example 1)
end points are always closed so every line on a shape is a line segment
to name them,
use the start and endpoint
with a line above the two letters
(make sure they are capitalized)
go alphabetically
(see example 4)
i hope that helps!
good luck going into 6th grade thats a tough one
