In the converse of a statement we switch the hypothesis with the conclusion.
Converse of the Statement: If ABCD is a parallelogram, then ABCD is a square.
Are They True? The statement is true and its converse is false.
We want to write the converse of the given statement. In this statement we have a hypothesis and a conclusion. A hypothesis tells us about the condition. When this condition is satisfied, the conclusion is true.

If {\color{#0000FF}{\underbrace{ABCD\text{ is a square}}_\text{hypothesis}}}, then ABCDis a parallelogram_(conclusion). |
Converse of the Statement |
If ABCDis a parallelogram_(new hypothesis), then {\color{#0000FF}{\underbrace{ABCD\text{ is a square}}_\text{new conclusion}}}. |
Let's think if our statement and its converse are true or false. To do so, let's recall that a parallelogram has two pairs of parallel sides.
A square is also a quadrilateral that has two pairs of parallel sides. Additionally, in a square all sides are congruent and all angles are right.
We can see that each square is a quadrilateral because it has two pairs of parallel sides. However, not every parallelogram is a square because a parallelogram does not have to have right angles or congruent sides. This means that our statement is true but the converse of the statement is false.
