| Question | Answer |
|---|---|
| *A location, shown as a dot. | points |
| *A set of all points. | space |
| *A long, thin continuous mark Types: straight, parallel, horizontal, vertical, intersecting, perpendicular, lines of symmetry, etc. | lines |
| *Three or more points that lie on the same straight line. | collinear |
| *A flat surface. | plane |
| *Points that do not lie on the same line. | non-collinear |
| * Geometric objects/figures that lie on the same plane | coplanar |
| *Geometric objects/figures that do not lie on the same plane. | non-coplanar |
| *To meet a some point, a common point or line. | intersect |
| *The set of points consisting of two endpoints and all points in between the endpoints. | segment |
| *A line that has a starting point, but it does not have an ending point. | ray |
| *Two rays with a common endpoint that form a line. | opposite ray |
| *The distance from one end to the other end *How long something is. |a-b| | length of a segment |
| *Having the same shape and the same size Example: A cube has congruent faces. | congruent segments |
| *The point in the middle of a line segment | midpoint of segment |
| *To divide in two equal sections *To cut in half | bisector of a segment |
| *If three points A, B, & C are collinear and B is between A and C, then AB+BC =AC. | segment addition postulate |
| *Lines that do not lie in the same plane in space, so that they cannot be parallel or intersect. | skew |
| *Lines that are the same distance apart at all points. They never intersect. | parallel |
| *Lines that intersect at right angles to each other. | perpendicular |
