A simply location
Point
Made up of points and has no thickness or width
Line
Points that lie on the same plane
Collinear
A flat surface made up of points
Plane
Points that lie on the same plane
Coplanar
Is a boundless, three-dimensional set of all points
Space
Segment, cam be measured because it has two endpoints
Line segment
They are only explained using examples and descriptions
Undefined terms
Any measurement depends on the smallest unit available for the measuring tool
Precision
A segment is the point on the segment that divides the segment into two congruent segments
Midpoint
Any segment, line, or plane that intersects a segment at its midpoint
Segment bisector
Is part of a line
Ray
Point determines exactly two rays
Opposite rays
Is formed by two noncollinear rays that have a common endpoint
Angle
The common endpoint
Vertex
A ray that divides an angle into two congruent angles
Angle bisector
A set of points that satisfy a particular condition
Locus
When segments have the same measure
Congruent
