Properties from Algebra

1-7) Match each statement with the appropriate property of equality.

Justify each statement with a property from algebra or definition or postulate from geometry.

8) If AB = CD and BC = BC, then AB + BC = CD + BC

9) If 3m∠1 = 93 then m∠1 = 31

10) BC ≅ BC

11) If point A is on the interior of ∠XOY, then m∠XOA + m∠AOY = m∠XOY

12) If m∠1 = m∠3 and m∠2 = m∠3, then m∠1 = m∠2.

13) If AB ≅ CD and CD ≅ EF, then AB ≅ EF.

14-15) 14) Complete the proof.
