2. Lines?
A straight path that has NO thickness and extends FOREVER
3. Plane
A flat surface w/o a thickness and extends forever
4. 1.Collinear
2.Non-collinear
• 1. Points that line on the same line
• 2.Points not on the same line.
5. 1-Coplanar
2-Noncoplanar
• 1-Points on the same plane
• 2-Points not on the same plane
6. Segment
Part of a line consisting of 2 points
7. Endpoint
Point at the end of the segment
8. Ray
Part of the line that starts at an end and goes forever
9. Opposite Rays
2 Rays that have common endpoints
10. Postulate
Statement accepted as true but without proof.
11. 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
12. Congruent segment
Segments that have the same length. You MUST put line over letter. Tick marks also.
13. Between
All three points musty lie in the same line
14. P1.2.2
If B is BETWEEN A and C then AB+BC=AC
15. Midpoint
Point that bisects the segment equally
16. A)Acute
B)Obtuse
C)Right
• A)Angle is less then 90
• B)Angle greater than 90
• C)Angle of 90. Must have Square
17. Vertex
Point where two line meet of an angle.
