Geometric proofs are logical arguments that demonstrate the truth of geometric statements using definitions, postulates, and previously established theorems. They often involve diagrams to visually represent the concepts being discussed, making it easier to understand the relationships between different geometric figures. In a geometric proof, each step is clearly stated and justified, leading to a conclusion that confirms the original statement. Common types of proofs include two-column proofs, paragraph proofs, and flowchart proofs, each providing a structured way to present the reasoning behind geometric concepts such as congruence, similarity, and the properties of shapes like triangles and circles.
