Answer:
If a polygon has congruent angles and congruent sides, then it is regular.
Step-by-step explanation:
If we have a statement,
'P is true if Q is true',
Then the statement 'Q is true if P is true' is called the converse statement of the above statement.
That is, the converse statement is obtained after switching the hypothesis and conclusion.
Thus, by the above explanation, It is clear that the converse of the statement,
'If a polygon is regular, then it has congruent angles and congruent sides'
Would be 'If a polygon has congruent angles and congruent sides, then it is regular'.
Hence, first option is correct.
