| Question | Answer |
|---|---|
| acute angle | an angle whose measure is between 0 and 90 |
| angle | formed by two rays with the same endpoint |
| angle bisector | a ray that divides an angle into two congruent angles |
| collinear points | collinear points lie on the same line |
| congruent angles | angles that have the same measure |
| congruent segments | segments that have the same length |
| conjecture | a conclusion reached by using inductive reasoning |
| coordinate | a point on a line or plane |
| coplanar | points or lines on the same plane |
| counterexample | proves a conjecture false |
| inductive reasoning | based on a pattern of past events |
| line | has no lenght, no width, or thickness. It extends with no end in two directions |
| midpoint | the point that divides the segment into two congruent segments |
| obtuse angle | an angle whose measure is between 90 and 180 |
| oppostie rays | collinear rays with the same endpoint |
| parallel lines | two lines are parallel if they lie on the same plane and do not intersect |
| perpendicular lines | lines that intersect and form right angles |
| plane | contains no thickness, and extends without end in the direction of its lines |
| point | a location on a line or plane |
| postulate | an accepted statement of fact |
| ray | the part of a line consisting of one endpoint and all the points of the line on one side of the endpoint |
| right angle | an angle whose measure is 90 |
| segment | the part of the line consisting of two end points and all points between them |
| skew lines | lines that do not lie on the same plane |
| space | the set of all points |
