(#89 - 103) Give a reason to justify each statement. 89. If AB & CD, then AB - CD. 90. mZY - mcB and mzB - mzC, then mZY = mzC. 91. If X is between A and B, then AX + XB - AB. 92. If 21 and 22 are supplementary, then mz1 + mz2 = 180. 93. If mzX = 90, then ZX is a right angle. 94. If 21 and 42 are vertical angles, then 21 = 42. 95. If X is the midpoint of CD, then CX a DX. _96. If mZA = mZB, then ZA = ZB. 97. If ZA and ZB are a linear pair, then mZA + mZB = 180. 98. If 42 and 24 are a linear pair, then 42 and 24 are supplementary. _99. If FR bisects ZAFP, then LAFR = ZFRP. 100. If AB = CD + EF and CD = 10, then AB = 10 + EF. 101. AB = AB -102. In AABC, if AB = BC, then AABC is isosceles. 103. If 42 and 23 are right angles, then 42 = 43. 104. Given: LP bisects ZMLN, NIT Nd 'WIT Wd Prove: PM ~ PN Statements Reasons 1. TP bisects ZMLN 1. 2. ZNLP = ZMLP 2. _ 3. PM 1 LM, PN J. IN 3. 4. ZLMP and ZLNP are right angles 4. 5. ZLMP = LLNP 5. - 6. 6. Reflexive 7. ALMP = ALNP 7. 8. PM = PN
