2.6 Prove Statements about Segments and Angles
... Prove the following: 1. Segment congruence is reflexive 2. Angle congruence is symmetric To do these proofs, you have to turn “congruence” into “equality” and then turn “equality” back into “congruence.” In either case, just apply the Definition of Congruent Segments or Angles. ...
