25 26 Chapter 1 Vocabulary

Front

has no size; length, width, or height. It is represented by a dot and named by a capital letter

Back

Point

Answer explanation

A point has no size, length, width, or height, and is represented by a dot. It is named by a capital letter, distinguishing it from other geometric figures like lines, rays, and planes.

Front

Set of points which has infinite length but no width or height. It is named by a lower case, cursive letter or by any two points on it

Back

line

Answer explanation

The set of points described is a line, which has infinite length but no width or height. It can be named using a lowercase cursive letter or by any two points on it, distinguishing it from curves, angles, and planes.

Front

a flat surface made of points that have infinite length and width but no height. It is named with three points that are not on the same line or by a capital ‘funny font’ letter

Back

Plane

Answer explanation

A plane is defined as a flat surface with infinite length and width but no height. It can be named using three non-collinear points or a capital letter, making 'Plane' the correct answer.

Front

Points that lie on the same line

Back

Collinear points

Answer explanation

Collinear points are defined as points that lie on the same line. The other options do not describe this relationship, making 'Collinear points' the correct choice.

Front

points that do NOT lie on the same line

Back

noncollinear

Answer explanation

The correct choice is 'noncollinear' because it describes points that do not lie on the same line. 'Collinear' refers to points that do lie on the same line, while 'noncoplanar' and 'coplanar' relate to planes, not lines.

Front

points that lie on the same plane

Back

Coplanar points

Answer explanation

Coplanar points are defined as points that lie on the same plane. In contrast, divergent points and noncoplanar points do not share this property, while collinear points refer to points on the same line, not necessarily a plane.

Front

points that do NOT lie on the same plane

Back

Noncoplanar points

Answer explanation

Noncoplanar points do not lie on the same plane, while collinear points lie on a line, coplanar points lie on the same plane, and noncollinear points can still be coplanar. Thus, noncoplanar points are the correct choice.

Front

geometric drawing that uses a limited set of tools, usually a compass and a straightedge

Back

Construction

Answer explanation

The term 'Construction' refers to geometric drawing using a compass and straightedge, which aligns with the question's description. Other options like 'Sketching' and 'Illustration' do not specifically involve these tools.

Front

point that represents the end of a line segment or ray

Back

endpoint

Answer explanation

The correct answer is 'endpoint' because it specifically refers to the point that marks the end of a line segment or ray, distinguishing it from other terms like 'starting point' or 'midpoint'.

Front

part of a line that consists of two points called endpoints and all points between them

Back

Line segment

Answer explanation

A line segment is defined as the part of a line that includes two endpoints and all the points in between. This distinguishes it from a line, which extends infinitely, and a ray, which has one endpoint and extends infinitely in one direction.
