Conclusion

Justification

1.  4 and 6 are comp

2. mA = 90

3. X is the midpt of WR

4. XR = XY

5. A is between C and R

6. mC = mD

7. AB = CD and CD = ZR

8. m5 + m6 = 180

9. AGR and RGY are

linear pairs

Give one reason that justifies the following.

____________________1. mR = mR

____________________2. If AB  CD, then AB = CD.

____________________3. If mY = mB and mB = mC, then mY = mC.

____________________4. If X is between A and B, then AX + XB = AB.

____________________5. If 1 and 2 are supplementary, then m1 + m2 = 180.

____________________6. If mX = 90, then X is a right angle.

____________________7. If 1 and 2 are vertical angles, then 1  2.

____________________8. If X is the midpoint of CD, then CX  DX.

____________________9. If mA = mB, then A  B.

___________________10. If m3 + m4 = 90, then 3 and 4 are complementary.

___________________11. If 2 and 4 are a linear pair, then  2 and  4 are supplementary.

___________________12. If FR bisects AFP, then AFR  FRP.

___________________13. If 1 and 2 are congruent, then m1 = m2.

___________________14. If AB = CD + EF and CD = 10, then AB = 10 + EF.

___________________15. AB = AB

___________________16. If 2 and 3 are right angles, then 2  3.
