| A | B |
|---|
| point | one location, used to create geometric shapes |
| line | need at least 2 points to make one, goes on forever in both directions |
| collinear | 3 points on the same line |
| noncollinear | 3 points not on the same line |
| ray | has on distinct endpoint, goes on forever in one direction only |
| endpoint | point where a ray or segment ens |
| segment | has 2 disinct endpoints - has a measureable length |
| plane | defined by 3 noncollinear points, like the face of a box |
| parellel | 2 things that go in th same direction and do not intersect |
| perpendicular | lines that intersect at a 90 degree angle |
| skew | 2 things that do not intersect but are not parellel |
| centimeter | 1/100 th of a meter - contains 10 mm |
| millimeter | 1/1000 th of a meter |
| meter | a unit of linear measure a little longer than a yardstick |
| kilometer | 1000 meters - used to measure road distances |
| congruent | similar in shape and size, but not the same figure |
