Point?
Names a location and has NO size. Represented with dot.

Lines?
A straight path that has NO thickness and extends FOREVER

Plane
A flat surface w/o a thickness and extends forever

1.Collinear
2.Noncollinear
 1. Points that line on the same line
 2.Points not on the same line.

1Coplanar
2Noncoplanar
 1Points on the same plane
 2Points not on the same plane

Segment
Part of a line consisting of 2 points

Endpoint
Point at the end of the segment

Ray
Part of the line that starts at an end and goes forever

Opposite Rays
2 Rays that have common endpoints

Postulate
Statement accepted as true but without proof.

1) P1.1.1
2) P1.1.2
3) P1.1.3
4) P1.1.4
5) P1.1.5
 1)Through any two points there is exactly one line
 2)Through any three noncollinear points there is exactly one plane containing them
 3) If 2 points lie in a plane, then the line containg those points lie in the plane
 4) If two lines intersect, then they intersect in exactly one POINT
 5) If 2 planes intersect, then they intersect in exactly one line

Congruent segment
Segments that have the same length. You MUST put line over letter. Tick marks also.

Between
All three points musty lie in the same line

P1.2.2
If B is BETWEEN A and C then AB+BC=AC

Midpoint
Point that bisects the segment equally

A)Acute
B)Obtuse
C)Right
 A)Angle is less then 90
 B)Angle greater than 90
 C)Angle of 90. Must have Square

Vertex
Point where two line meet of an angle.
