Problem :
Can two-dimensional objects exist in three-dimensional space?
Yes. They simply exist in the same plane within space.
Problem :
What is the minimum number of lines it takes to span space?
Three
Problem :
Explain why three noncolinear points cannot form a three-dimensional object in
space?
A plane can be created to contain any three points in space, therefore,
three points isn't enough to create a three-dimensional object. It requires
four noncoplanar points to form a three-dimensional object.
