Question

(4) Any three points in the figure which are non-collinear.​

Answer 1

Non-collinear points: These points, like points X, Y, and Z in the above figure, don't all lie on the same line. Coplanar points: A group of points that lie in the same plane are coplanar. Any two or three points are always coplanar. Four or more points might or might not be coplanar.

Answer 2

Answer:Points B, E, C and F do not lie on that line. Hence, these points A, B, C, D, E, F are called non - collinear points. If we join three non - collinear points L, M and N lie on the plane of paper, then we will get a closed figure bounded by three line segments LM, MN and NL. This closed figure is called a Triangle.
