|---|---|
 point | I am a location in space. It takes only one letter to name me. |
| line | My length cannot be measured, but I am named by two of my points. |
| ray | I do not curve. I have only one endpoint. |
| angle | I am measured in degrees. I have a vertex. My sides are two rays. |
| perpendicular line segments | We have endpoints. When two of us meet, we form one or more right angles. |
| parallel line segments | There are always at least two of us. We have endpoints. We always stay the same distance apart. |
| vertex | I am the point where two rays meet to form an angle |
| intersecting lines | Two of us meet. |
| perpendicular lines | Our lengths cannot be measured. When two of us meet, we form right angles |
| vertices | I am the endpoint where two sides of a polygon meet |
| line segment | My length can be measured. I have two endpoints |
| parallel lines | Our lengths cannot be measured. There are always at least two of us. We always stay the same distance apart. |
