Question

The walls of a room are representations of what basic element of geometry? A. point B. line C. plane D. ray

Answer 1

The answer would be C. Plane.

Answer 2

In geometry,

A point represents a point

Two points define a line extended on both sides of the points.

Two points define a ray if it extends on only one side of either of the points.

Three or more than three points define a plane.

Now as far as a wall is considered, it is a flat surface on which we can plot infinite points.

Hence the wall represents a plane.

Option C) is the right answer.
