| Question | Answer |
|---|---|
| acute angle | an angle whose measure is between 0 and 90. |
| angle | two rays connected cut their endpoints.(the point is where they connect called the vertex) |
| angle bisector | a ray that divides an angle into two congruent angles |
| collinear points | lie on the same line |
| congruent angles | angles that have the same measure |
| congruent segments | segments with the same length |
| Conjecture | a conclusion reached by using inductive reasoning |
| Coordinate | a point on a line or plane |
| Coplanar | points or lines on same plane |
| counterexample | is a conclusion reached through inductive reasoning |
| inductive reasoning | is based on observed patterns |
| line | has no length,no width, or thickness. It extends without end in two directions. |
| midpoint | a point that divides a segment into two congruent segments |
| obtuse angle | angle more than 90 degrees and less than 180 degrees |
| opposite rays | starts at the same point and go in opposite direction |
| parallel lines | are coplanar lines that do not intresct |
| perpendicular lines | lines intersect to form right angle |
| plane | is a flat surface that has no thickness. It extends without end in all direction. *at least 3 noncollinear points to name a plane |
| point | has no length, width, or thickness just a postition |
| postulate | an accepted statement of fact |
| ray | is a part of a line that consits of an intital point and all points on the line that lie on one side of the intinal point |
| right angle | a angle that mesaure 90 degrees |
| segment | the part of the line consiting of two end points and all points between them |
| skew lines | lines that do not lie on the same plane; are noncoplanar lines (they are not parallel&dont intersect) |
| space | is the boundless 3-d set of all points |
