Question

A closed half plane, (Define)

Answer 1

Answer:

Step-by-step explanation:

A half-plane is a planar region with all the points on one side of an infinite straight row and no points on the other. If the points on the line are included, then it known as a closed half-plane.

Given a plane A, and any line q in the plane divides A into two parts, the two parts are called the half-planes. Since a plane extends infinitely in both the directions, therefore, each part is half of the plane. The line q may belong to either of these parts, but still both the parts will be half-planes regardless of whether or not line q is included.
