What is a Point?

Definition: Point

Summary

  1. Points are usually labeled with capital letters
  2. Often you will see points labeled on lines
  3. Points can also lie on planes
  4. Points can lie on angles, as well!
  5. Polygons, such as triangles, may contain points, too
  6. Naming geometrical shapes is made easier with points
  7. Endpoints are points that mark each end of a line segment
  8. A midpoint is the point halfway between the endpoints of a line segment

Notes

    1. Points are usually labeled with capital letters
    2. The first point we have drawn is labeled as point "A"
    1. Often you will see points labeled on lines
    2. Points "B" and "C" fall on the first line drawn here
    3. Points can also lie on planes, on angles, or on polygons
    4. Points are also used to name geometrical objects
    1. Endpoints are points that mark each end of a line segment
    2. A midpoint is the point halfway between the endpoints of a line segment
    3. A vertex is a point where the two rays that make up an angle intersect
