Given: BAT=CAT Which statement is true by CPCTC? A. CT=AT B. TAC=BTA C. BAT= CAT D. BT=TA Will give medal if you could help me figure out the answer...thanks....

Directrix (directrix):

I assume that this is Triangle BAT is congruent to Trianlge CAT. If two triangles are congruent, then corresponding parts are congruent.

Directrix (directrix):

Part means angle or side. There are 6 pairs of congruent corresponding parts.

Directrix (directrix):

I listed the three pairs of corresponding sides but not the angles.
