not line up”; we take our cue from the last part of that statement.
Choice cis not our answer.- b.A line segmentis the shortest distance between any two points.
- d.A line, a line segment, and a ray are sets of points. How many
points make a set? An infinite number. Since a limit cannot be put
on infinity, not one of the answer choices has more than the other.
Set 3
- Any six of these names correctly describe the line: RS, SR, RT,
TR, ST, TS, RST, and TSR. Any two points on a given line,
regardless of their order, describes that line. Three points can
describe a line, as well. - Two of the four rays can each be called by only one name: STand
SR. Ray names RTand RSare interchangeable, as are ray names
TSand TR; each pair describes one ray. RTand RSdescribe a
ray beginning at endpoint R and extending infinitely through •T
and •S. TSand TRdescribe a ray beginning at endpoint T and
extending infinitely through •S and •R. - SRand STare opposite rays. Of the four rays listed, they are the
only pair of opposite rays; they share an endpoint and extend
infinitely in opposite directions. - Line segments have two endpoints and can go by two names. It
does not matter which endpoint comes first. RTis TR; RSis SR;
and STis TS.
Set 4
- Any six of these names correctly describes the horizontal line: NP,
PN, NO, ON, PO, OP, NOP, PON. Any two points on a given
line, regardless of their order, describe that line.
