Coplanar
points that lie on the same plane
Coplanar is a term used in geometry to describe a set of points, lines, or planes that lie in the same plane. In simpler terms, it means that all the points, lines, or planes in question are situated on the same flat surface.
For example, if we have three points A, B, and C, we say that they are coplanar if they all lie on the same plane. Another example is a triangle. The three sides of a triangle are coplanar because they all lie on the same plane.
It is important to note that coplanar objects do not necessarily have to be positioned close to one another. They can be located anywhere in space, as long as they all lie in the same plane.
An understanding of coplanar is essential in various branches of mathematics, including geometry, trigonometry, and calculus, where it is used to determine the relationship and position between different objects.
