CPCTC and Isosceles and
Equailateral Triangles
Once you have triangles congruent, you can
make conclusions about their other parts
because, by definition, corresponding parts
of congruent triangles are congruent.
State why the two triangles are congruent. Give
the congruence statement then tell what other
parts are congruent by CPCTC.
