Definition of geometric center?

Geometric center is a photographic term, the intersection of two diagonal lines of a picture.

Generally, the main object is not placed in the geometric center, otherwise it is easy to make the picture composition appear dull, but if we pay attention to its structural changes, it can also be broken through. In general, the main performance object in photographic composition is placed at a position deviating from the geometric center.

Only regular figures have geometric centers, such as squares and regular triangles.

And each geometric figure has a geometric center of gravity. For example, a triangle is the intersection of three midlines. When it is a regular geometric figure with uniform medium, the geometric center of gravity is at the geometric center.

The center of gravity is the point where the resultant force of gravity of all constituent particles passes through the gravity field when the object is in any direction.

Introduction to geometry:

Geometry is the study of spatial structure and properties. It is one of the most basic research contents in mathematics, which has the same important position as analysis and algebra, and has a very close relationship. Geometry has a long history and rich contents. It is closely related to algebra, analysis and number theory. Geometric thought is the most important thought in mathematics.

The earliest records can be traced back to ancient Egypt, ancient India and ancient Babylon, which began around 3000 BC.

Early geometry is an empirical principle about length, angle, area and volume, which is used to meet the practical needs of surveying and mapping, architecture, astronomy and various crafts.
