I Can Use the properties of equality to complete algebraic proofs. Identify properties of equality and congruence.

Proofs A proof is an argument that uses logic, definitions, properties and previously proven statements to show that a conclusion is true. If you’ve ever simplified an expression or solved and equation in Algebra, then you’ve done a proof.
