Any Euclidean plane has infinitely many points.
Noncollinear points are points which are not all on a common line.
no
exactly one and only one.
Only one plane can pass through 3 non-collinear points.
yes. For example the corners of a square, or on the circumference of a circle.
No. For example, consider the vertices of a tetrahedron (triangle-based pyramid).
noncollinear
A plane
Since collinear is points that lie on the same line, and you need two points to form a line so those 2 points are collinear. So the opposite of that is noncollinear.
Any Euclidean plane has infinitely many points.
No. Any two points can be made to form a line.
