a segment is a point that divides a segment into two congruent segments. A midpoint, or any line, ray, or other segment through a midpoint, is said to bisect the segment
Skew lines
are noncoplanar, therefor, they are not parallel and don't intersect
Parallel lines
Are coplanar lines that don't intersect.
Opposite rays
ate two collinear rays with the same endpoint. Opposite rays always form a line.
Ray
The part of a line consisting of one end point and all the points of the line on one side of the endpoint.
Segment
The part of a line consisting of two endpoints and all points between them.
Postulate or axiom
is an accepted statement of fact
Coplanar
Points and lines in the same plane
Plane
is a flat surface that has no thickness
Collinear Points
Points that lie on the same line
line
A series of point that extends in two opposite directions without end. you can name a line by any two points on the line.
Space
is defined as the set of all points
Point
A point has no size.. It is represented by a small dot and is named by a capital letter..
Counterexample
To a conjecture is an example for which the conjecture is incorrect.
Conjecture?
A conclusion you reach using inductive reasoning.
Inductive reasoning?
The reasoning that is based on patterns you observe. If you observe a pattern in a sequence, you can use inductive reasoning to tell what the next terms in the sequence will be.
