Question

what is collinear and coplaner points ???

Answer 1

Collinear points are points all in one line and noncollinear points are points that are not on one line. Below points A, F and B are collinear and points G and H are non collinear. Coplanar points are points all in one plane and non coplanar points are points that are not in the same plane.

Answer 2

◆Collinear point=Three or more points , , , ..., are said to be collinearif they lie on a single straight line . A line on which points lie, especially if it is related to a geometric figure such as a triangle, is sometimes called an axis. Two points are trivially collinear since two points determine a line.
◆Coplaner point=Coplanar points are three or more points which lie in the same plane. Recall that a plane is a flat surface which extends without end in all directions. It's usually shown in math textbooks as a 4-sided figure.
