3 a Given A F and −−
AB −−
EF . −−−
AD −−
CF and by the reflexive property of
congruence −−−
DC −−−
DC . By the addition postulate, −−−−
ADC −−−
FCD . Therefore, by SAS,
ABC DEF.
2 a An appropriate proof with correct conclusions is shown, but one reason is faulty
and/or one statement is missing.
1 a A correct conclusion is reached and a reason is given, but no appropriate method
is shown.
3 b Given D A. C is the midpoint of −−−
AD , then −−
AC −−−
DC .
ACB DCE because vertical angles are congruent. Therefore,
by ASA, ABC DEC.
2 b An appropriate proof with correct conclusions is shown, but one reason is faulty
and/or one statement is missing.
1 b A correct conclusion is reached and a reason is given, but no appropriate method
is shown.
0 A zero response is completely incorrect, irrelevant, or incoherent or is a correct response
that was obtained by an obviously incorrect procedure.
