Types of Statements
Many people use logic and deductive reasoning in performing their tasks. In geometry, you begin with accepted statements and properties, then use logic and deductive reasoning to prove other statements.
Logic allows you to evaluate the correctness of arguments and reasoning. Arguments are composed of several statements that are either true or false, but not both.
