PRACTICE! Justily each statement below using a properly of equality, property of congruence, definition, or postulate. CO 1. If PQ = PO. then PQ = PO 1 . Yeflex ive Property 2. If &' is between J and L, then JK + KL = JL |2. Transitive Property 3. EF = EF 3. Symmetric property 4. If RS = TU. then RS + XY = TU + XY 4. Transitive Property 5. If AB = DE, then DE = AB 5. Symmetric Property 6. If Y is the midpoint of XZ , then XY = Yz 6. Definition of Midpoint 7. II FG = HI and HI = JK , then FG = JK 7. Transitive property B. If AB + CD = EF + CD). then AB = RF 8 . Transitive Property 9. If PO + RS = TV and RS = WX, then PQ + WX = TV 9. Substitution property 10. If I.P = PN, and 1, P. and N are collinear, then P is the midpoint of IN 10 11. If UV = UV , then UV = UV 11. Definition of congruence 12. If CD + DE = CE, then CD = CE-DE 12. Segment addition Postulat 13. If 2XY = XZ, then XY = = XZ 13. 14. If RS = ST and ST = 2UV. then RS = 2UV 14.
