Question

three points are collinear.
always
never
sometimes

Explanation:

Collinear points are points that lie on the same straight line. While it's possible for three points to be collinear (e.g., three points on the x - axis: (1,0), (2,0), (3,0)), there are also many cases where three points are not collinear (e.g., the vertices of a triangle). So three points are collinear only sometimes.

Answer:

sometimes
