Geometry and Architecture... They are two subjects that the world associates side by side. But, what are the basic concepts of Geometry that allow the creativity of the architect to be placed on paper?

The first concept of Geometry is a point. A point is a zero-dimensional figure that pinpoints a specific location in space. It has no length, width, or depth. But it plays one of the most important role in making blueprints. It allows architects to specify the place of intersection between two or more edges.

A line is a one dimensional figure with two points that it goes through. It is infinite in both directions. In Architecture, a line serves as an edge, the outer limit of an object, shape, or area. Architects also use lines to signify walls in buildings when drawing from an aerial perspective.

A ray is a line with one endpoint, the side without an endpoint extends infinitely. When an architect draws a new building, the ray is the grid that the building is drawn upon to make sure of symmetry and stability.

A plane is a two dimensional figure with length and width, but no depth. For an architect, a plane signifies the face of a building or a structure.

These figures are essential in pointing out where there are edges, vertices, corners, and sides of a building. They help an architect visualize all three dimensions of the building and where one side injects into another. This concept is most useful for the drawing portion of an architect's job.
