To write the converse of a conditional, switch the hypothesis and the conclusion. You may need to adjust the language a little.
Conditional:
If a polygon is a pentagon, then it has five sides.
The hypothesis is "a polygon is a pentagon."
The conclusion is "it has five sides."
Now switch the hypothesis and the conclusion and adjust the language a little.
Converse:
If a polygon has five sides, then it is a pentagon.
As you can see, the hypothesis and conclusion were switched to form the converse.
Every five-sided polygon is a pentagon, and every pentagon is a five-sided polygon, so both the conditional and the converse are true.
