Planar surfaces
Planar surfaces refer to flat, two-dimensional surfaces that extend infinitely in width and length but have no thickness. In geometry, a plane is defined by three points that are not collinear. Common examples of planar surfaces include sheets of paper, tables, or any flat area. In various fields such as architecture, engineering, and computer graphics, understanding planar surfaces is crucial for designing and analyzing structures, objects, and spaces. Essentially, planar surfaces serve as the foundation for many concepts in mathematics and real-world applications, making them fundamental to our understanding of shapes and forms.
