3. 3. Point <ul><li>A point is something that has a position but takes up no space or volume. It usually defines a line segment’s endpoints or a positions on a plane. </li></ul>
4. 4. Line Segment <ul><li>A line segment is a broken part of a line with two endpoints </li></ul>
5. 5. Plane <ul><li>A plane is a flat surface created by at least three or more points. When 3 points make a plane they are coplanar. </li></ul>
6. 6. Angle <ul><li>An angle occurs when two rays with the same endpoint jut out in different directions. </li></ul>

20. 20. Vertex <ul><li>A vertex is a point that connects two or more lines that make a shape or figure. </li></ul>
21. 21. Line <ul><li>A line is a flat extension that has no width an goes on forever in both directions </li></ul>
