Inductive Reasoning
Based on patterns you observe.
Conjecture
A conclusion you reach using inductive reasoning.
Counterexample
An example which the conjecture is INcorrect.
Point
A location.
Space
Defined set of all points.
Collinear Points
Points that lie on the same line.
Segment
Part of a line consisting of two endpoints and all points between them.
Ray
Part of line consisting one endpoint and all points of line on one side of endpoint.
Postulate or Axiom
An accepted statement or fact.
Plane
Flat surface with no thickness.
Parallel Planes
Planes DO NOT intersect.
Parallel Lines
Coplanar lines DO NOT intersect.
Opposite Rays
Two collinear rays with the same endpoint.
Line
A series of points that extends in two opposite directions without end.
Coplanar
Points and lines in the same plane.
Skew Lines
Noncoplanar, not parallel and DO NOT intersect.
Adjacent Angles
2 coplanar angles /w/ common side, vertex, + no common interior points.
Vertical Angles
2 angles whose sides re opposite rays.
Supplementary Angles
2 angles measures sun to 180.

Congruent Segment
2 segments /w/ the same length.
Congruent Angles
Angles /w/ same measure.
Complementary Angles
2 angles measures sum to 90.
Angle
Formed by 2 rays /w/ same endpoint.
