Meaning of geometry (what is it, concept and definition)

What is Geometry:

Geometry is a branch of Mathematics that studies the properties and characteristics of figures on a plane or in space and their relationships.

It comes from the Latin geometry , and in turn from the Greek γεωμετρία , formed by the terms γεω ( gueo , 'earth') and μετρία ( metry , 'measure').

Analytic geometry

Analytical geometry is the study and representation of geometric elements and figures using numerical and algebraic expressions in a coordinate system or Cartesian plane. It allows the representation of figures through formulas. This type of geometry is applied, for example, in Physics to represent elements such as vectors in a coordinate system.

Descriptive geometry

Descriptive geometry is the study and graphic representation of figures through orthogonal projection on a plane. It allows to identify and analyze the geometric properties and the spatial relationship of the figures. The geometric elements that form it are the point, the line, the plane and the volume.

Euclidean geometry

Euclidean lageometry is the study of the geometric properties of Euclidean spaces. Also known as Euclidean geometry and sometimes parabolic geometry. It is based on the postulates of the Greek mathematician Euclid. It includes plane geometry (two dimensions) and space or spatial geometry (three dimensions).

Plane geometry

Plane geometry is the part of geometry that studies the figures represented on a plane (in two dimensions: length and width).

Molecular geometry

Molecular geometry is the study of the structure of the atoms that make up a molecule. It is also sometimes known as a molecular structure. The arrangement of atoms determines the physical and chemical properties of a molecule.

Some examples of the geometric shape that a molecule can have are: linear, tetrahedral and angular (for example the water molecule).
