The type of reasoning based on definitions, postulates, and theorems is called deductive reasoning. In this process, conclusions are drawn logically from established premises, allowing for the derivation of new truths from known facts. This method is fundamental in mathematics and logic, where the validity of arguments relies on the structure of the reasoning rather than empirical evidence.
The four components of proofs in geometry are definitions, axioms (or postulates), theorems, and logical reasoning. Definitions establish the precise meanings of geometric terms, while axioms are foundational statements accepted without proof. Theorems are propositions that can be proven based on definitions and axioms, and logical reasoning connects these elements systematically to arrive at conclusions. Together, they form a structured approach to demonstrating geometric relationships and properties.
A theorem is a mathematical statement or proposition that has been proven to be true based on previously established axioms, definitions, and logical reasoning. It serves as a foundational element in mathematics, providing a framework for further exploration and discovery. Theorems are often accompanied by proofs that demonstrate their validity.
An accepted statement of fact that is used to prove other statements in mathematics is called a "theorem." Theorems are established based on previously proven statements, known as axioms or postulates, and can be further supported by proofs that demonstrate their validity. These foundational principles serve as the building blocks for mathematical reasoning and problem-solving.
In mathematics, a known fact refers to a statement or proposition that has been proven to be true based on established definitions, axioms, and theorems. These facts serve as the foundation for further reasoning and problem-solving within mathematical contexts. They are accepted universally within the mathematical community and can be relied upon to derive new results or solve mathematical problems. Examples include basic arithmetic properties, geometric theorems, and algebraic identities.
Euclid is often referred to as the "Father of Geometry" for his systematic compilation and organization of mathematical knowledge in his work "Elements." In this influential text, he presented the principles of geometry based on definitions, postulates, and proofs, laying the groundwork for modern mathematics. Euclid's method of logical deduction and rigorous proof set the standard for mathematical reasoning and education for centuries.
The four elements of a deductive structure are the premise, inference, deduction, and conclusion. The premise is the starting point or evidence, the inference is the logical reasoning process, the deduction is the application of a rule or principle, and the conclusion is the final outcome or assertion based on the premises and inference.
You start out with things that you know and use them to make logical arguments about what you want to prove. The things you know may be axioms, or may be things you already proved and can use. The practice of doing Geometry proofs inspires logical thinking, organization, and reasoning based on facts. Each statement must be supported with a valid reason, which could be a given fact, definitions, postulates, or theorems.

Deductive reasoning is usually based on laws, rules, principles, generalizations, or definitions. It involves drawing specific conclusions from general principles or premises.

Geometry has a variety of applications from engineering to the physical sciences. It is also used in construction and art. However, most would probably never use a theorem from geometry directly. So why do we study the theorems of geometry? It has to do with learning to think clearly and critically. Theorems are deduced based on axioms and rules of logic. Learning to prove the theorems or even just understand them can do much to increase your reasoning skills. With better reasoning skills you can distinguish good arguments from bad ones and increase your problem solving ability.
objective means that you make decisions and draw conclusions based on evidence, subjective means that personal feelings have entered into a decison or conclusion.
