| Question | Answer |
|---|---|
| acute angle | less than 90 degrees |
| angle | made of 2 rays connected at their endpoints, the point where they connest is the vertex |
| angle bisector | cutting angle into two congruent angles |
| collinear points | points that lie on the same line |
| congruent angles | angles with the same measurements |
| congruent segments | two segments with the same length "~ over = sign" means " congruent to" |
| conjecture | a conclusion reached through inductive reasoning(remember the conjecture seems, but it is unproven) |
| coordinate | The coordinate of a point ios its distance and direction from the origin of a number line |
| coplanor | points & lines in the same plane |
| counterexample | a single couter example is enough to disprove a conjecture |
| inductive reasoning | is reasoning based on ibserved patterns (we assume the observed pattern will continue) |
| line | has no length, width, or thickness. It extends in 2 directions |
| midpoint | a point that divides a segment into two congruent segments |
| obtuse angle | more than 90 degrees |
| opposite rays | starts at the same point and goes in the opposite direction |
| parallel lines | are planes that do not intersect |
| perpendicular lines | lines that intersect to form right angles |
| plane | is a flat surface that has no thickness. It extenbd without end in all directions |
| point | has no length width or thickness but has a position |
| postulate | statement accepted to be true without proof |
| ray | a part nof a line that consist of an intial point and all points on the line that liee on side of the initial point |
| right angle | exactly 90 degrees |
| segment | a portion of a line |
| skew lines | are noncoplanor lines therefore they are not parallel and do not intersect |
| space | 3 dimensional set of all points boundless |
