Final answer:
The converse, inverse, and contrapositive of the conditional statement "If a polygon is regular, then all of its angles are congruent" are, respectively: "If all of a polygon's angles are congruent, then the polygon is regular," "If a polygon is not regular, then not all of its angles are congruent," and "If not all of a polygon's angles are congruent, then the polygon is not regular."
Step-by-step explanation:
The conditional statement given is "If a polygon is regular, then all of its angles are congruent."
- The converse of the conditional statement would be "If all of a polygon's angles are congruent, then the polygon is regular."
- The inverse of the conditional statement would be "If a polygon is not regular, then not all of its angles are congruent."
- The contrapositive of the conditional statement would be "If not all of a polygon's angles are congruent, then the polygon is not regular."
These logical forms are useful for constructing valid arguments and understanding relationships between propositions in fields like mathematics and philosophy.
