I think the question you mean to ask is, "Do three collinear points make a triangle?" Linear is simply the adjective form of "line", "collinear" is used to describe points that lie on the same line. (Two points not only can be collinear, but always are, so it makes little sense to describe them as such).Collinear points cannot make a triangle, a triangle requires three noncollinear points.

False. Three collinear points determine a line while three non-collinear points determine a plane ( A Triangle)

Three non-collinear points do not determine a unique spherical triangle.

a triangle is formed by line segments that connect two non-collinear points

No, A plane can be drawn through any 3 points. If the 3 points are collinear then they make a line and a plane can contain a line. If the points are noncollinear then they can be used to form the corners of a triangle; all points of a triangle are in the same plane.

The following is the answer.

False. Three collinear points determine a line while three non-collinear points determine a plane ( A Triangle)

That they are not collinear.

its a triangle

No. Not if they are collinear (on the same straight line).

a triangle

False.

Collinear pointsPoints that lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are non collinear points.
