Answer the following statement(s) true (T) or false (F)
1. If two triangles are congruent, then there are exactly three pairs congruent parts—the
corresponding angle pairs.
2. In ?ABC, if then ?BAC ? ?ACB.
3. If AB , ? XY, BC ? YZ and ?ABC ? ?XYZ then ?ABC ? ?XYZ
4. In ?ABC, ?ABC ? ?CBA by corresponding parts (C.P.)
5. If PQ bisects AB,then AP ? BP.
1. False:There are six pairs of congruent parts.
2. True
3. False: SSA is not a valid congruence condition.
4. False: By Identity
5. False— PQ must be perpendicular to AB to reach the conclusion.
