| Question? | Answer. |
|---|---|
| What has no length, width, or thickness, but has a position | Point |
| What is the definition of space? | The boundless 3-dimensional set of all points |
| What ha no length, no width, or thickness, it extends with end in two directions. | Line |
| Points that lie on the same line are what? | Colilinear Points |
| Define plane. | A flat surface that has no thickness,it extends without end in all directions. |
| Points an d lines in the same plane are? | Coplaner |
| What do intersecting lines share? | They shaare a point. |
| A statement accepted to be true without proof is known as what? | Postulate |
| What is a line segment? | It is a portion of a line between two points, called endpoints. |
| What is part of a line that consits of an initial point abd all points on the line that lie on one side of the initial point. | Ray |
| What are parallel line? | Coplaner lines that do not intersect. |
| Lines that are noncoplaner, therefore, they are not parallel and do not intersect are what? | Skew Lines |
| Lines that intersect to form right angles are what kind of lines? | Perpindicular Lines |
| Opposite Rays | These start at the smae, and go in opposite directions. |
| What are right angles? | Angles that are exactly 90 degrees |
| Angles that are larger than 90 degrees but less than 180 are? | Obtuse angles |
| Two segments with the same length are? | Congruent Segments |
| What is a midpoint? | A point that divides a segment into two congruent segments, it bisects the segment. |
| What are angles? | Two rays that are connected at their endpoints calles the vertex. |
| Angles are have the same measure of degree are? | Congruent Angles |
| What does an angle bisector do? | Cuts an angle into two congruent angles |
| What is inductive reasoning? | A reasoning based on observed patterns |
| A conclusion reached through inductive reasoning is what? | Conjecture |
| What is a counter-example? | An example enough to disporve a conjecture |
| Points and lines in the same plane are what? | Coplaner |
| What are coorinates? | Numbers associated with a point on a line |
