II. Questions to Ponder:
1. Consider the stars in the night sky. Do they represent points?
2. Consider the moon in its fullest form. Would you consider a full moon as a
representation of a point?
3. A pencil is an object that represents a line. Does a pencil extend infinitely in both
directions? Is a pencil a line?​

Sagot :

brrrry

Answer:

  1. Yes, they could represent points.
  2. A point does not have any physical dimension. So a full moon as a representation of point would be a bit weird. But it could be a representation of a plane.
  3. I've never seen a pencil that extends infinitely, so no. Still, a pencil could represent a line; it would be called a line segment, though.
