New cards
16

infinite length

Whereas a line has ________, a line segment has a finite length.

New cards
17

Dimension

________- The number of lines required to span a region in space.

New cards
18

straight formation

A line is the infinite set of all points arrayed in a(n) ________.

New cards
19

Collinear

Lying in one line (usually refers to a set of points)

New cards
20

Congruent

Of exactly the same size and shape; in other words, of exactly the same dimensions

New cards
21

Coplanar

Existing in one plane (usually refers to points or lines)

New cards
22

Dimension

The number of lines required to span a region in space

New cards
23

Line

A collection of points arrayed in a straight formation without limit

New cards
24

Noncollinear

Not lying in one line (usually refers to a set of points)

New cards
25

Noncoplanar

Not existing in one plane (usually refers to points or lines)

New cards
26

Perpendicular

At a 90 degree angle (something is perpendicular relative to something else)

New cards
27

Plane

A flat, boundless surface in space

New cards
28

Point

A specific location in space

New cards
29

Ray

A portion of a line with a fixed endpoint on one end that extends without bound in the other direction

New cards
30

Segment

A portion of a line with two endpoints and, thus, finite length

New cards
31

Space

The collection of all points

New cards
32

To put it another way, there is only one way that you can move along a line

lengthwise

New cards
33

Therefore a line is one

dimensional

New cards
34

It requires two lines to span a plane, so therefore a plane is two

dimensional

New cards
35

Imagine a box

It has length, width, and height

New cards
