PROPERTIES OF EQUALITY

In Geometry deductive reasoning is used to prove conjectures and theorems. In this unit you will begin to examine a logical procedure for verifying geometric relationships. You will start with reviewing the “properties of equality” for real numbers, and then relate them to geometric measures. You will apply the reflexive, symmetric, transitive, and substitution properties to provide reasons for geometric statements and to write informal proofs.
