  2. 2. Point <ul><li>An undefined term in geometry. It names a location and has no size. </li></ul><ul><li>*Registration and inspection stickers on a windshield are examples of points on a plane. </li></ul>
  3. 3. Line Segment <ul><li>A part of a line consisting of two endpoints and all points </li></ul>between them.
  4. 4. Plane <ul><li>A flat surface that has no thickness and extends forever. </li></ul>
  5. 5. Angle <ul><li>A figure formed by 2 rays, or sides, with a common endpoint. </li></ul>
  6. 6. Perpendicular lines <ul><li>Lines that intersect at 90 degrees. </li></ul>
  7. 7. Parallel Lines <ul><li>Coplaner lines that do not intersect. </li></ul>

  17. 17. Cylinder <ul><li>A three-dimensional figure with two parallel congruent circular bases and a curbed lateral surface that connects the bases. </li></ul>
  18. 18. Sphere <ul><li>The set of points in space that are a fixed distance from a given point called the center of the sphere. </li></ul>
  19. 19. Octagon <ul><li>An eight-sided polygon. </li></ul>
  20. 20. Oval <ul><li>A closed plane curve resulting from the intersection of a circular cone and a plane cutting completely through it. </li></ul>
  21. 21. Skew Lines <ul><li>Lines that are not coplaner. </li></ul>
