Intro to Geometry (points, lines, dimensions, etc.)

Coplanar

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

Dimension

________ is a characteristic of all geometric regions, objects, and spaces.

Noncoplanar

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

straight formation

Line- A collection of points arrayed in a(n) ________ without limit.

boundless surface

A plane is a(n) ________ in space.

Height

________ is a measurement of length perpendicular to length and width.

Collinear

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

Noncollinear

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

P

A plane is denoted by writing "plane , "or just writing ".

ray

A(n) ________ is a cross between a line and a line segment.

Congruent

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

Segment

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

Collinearity

________ is a relative term.

Geometry

________ is the study of shapes.

new dimension

Space is three- dimensional; that is, it has length, width, and a(n) ________, height.

infinite length

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

Dimension

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

straight formation

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

Collinear

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

Congruent

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

Coplanar

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

Dimension

The number of lines required to span a region in space

Line

A collection of points arrayed in a straight formation without limit

Noncollinear

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

Noncoplanar

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

Perpendicular

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

Plane

A flat, boundless surface in space

Point

A specific location in space

Ray

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

Segment

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

Space

The collection of all points

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

lengthwise

Therefore a line is one

dimensional

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

dimensional

Imagine a box

It has length, width, and height
