| ray | a part of a line consisting of one point, and all the points on one side of the line from that point |
| skew lines | non-coplanar lines - they are lines that do not intersect but are not parallel |
| vertex | the common endpoint where two rays intersect to form an angle |
| endpoints of a segment | the points used to name a part of a line called a segment |
| venn diagram | a diagram that can help illustrate a relationship between subsets |
| degree | a unit used to measure the size of an angle |
| point | a specific location, it has no size, but can be modeled by a dot |
| endpoint of a ray | Point A would be the midpoint of ray AB or the beginning of the ray |
| angle | Two rays (that are not collinear) with a common endpoint |
| counterexample | an example that shows an example to be false |
| net | a pattern that can be cut out and folded up into a three-dimensional figure |
| measure of an angle | Measure between 0 and 180 degrees. We use a protractor to measure angles |
| line of reflection | the line over which a pre-image is reflected to produce its image |
| conjecture | a conclusion based on observation |
| reflection image | the image produced by a transformation |
| isometric drawing | a special type of drawing that helps to show the connection between perspective and orthographic views. Parallel edges are actually parallel. |
| orthographic view | same as orthogonal - shows objects exact shape and dimensions |
| orthogonal view | shows objects exact shape and dimensions |
| constuction | a technique for a drawing precise figures using only a straightedge and compass |
| pre-image | the figure to which a transformation is applied, producing its image |
