# Geometry definitions postulates and theorems

Overview Contemporary geometry has many subfields: Differential geometry uses techniques of calculus and linear algebra to study problems in geometry. It has applications in physicsincluding in general relativity. Topology is the field concerned with the properties of geometric objects that are unchanged by continuous mappings.

In order to study geometry in a logical way, it will be important to understand key mathematical properties and to know how to apply useful postulates and theorems.

A postulate is a proposition that has not been proven true, but is considered to be true on the basis for mathematical reasoning.

Free geometry papers, essays, and research papers. The Father Of Geometry - Euclid was born back in three hundred BC in Alexandria Greece and died at the age of . Since non-Euclidean geometry is provably relatively consistent with Euclidean geometry, the parallel postulate cannot be proved from the other postulates.

In the 19th century, it was also realized that Euclid's ten axioms and common notions do not suffice to prove all of the theorems stated in the Elements.

GEOMETRY POSTULATES AND THEOREMS Postulate 1: Through any two points, there is exactly one line. Postulate 2: The measure of any line segment is a unique positive number. The measure (or length) of AB is a positive number, AB. Postulate 3: If X is a point on and A-X-B (X is between A and B), then AX + XB = AB Postulate 4: If two lines intersect, then they intersect in exactly one point.
