Consider the following statement:

A figure is a square. Its diagonals divide it into isosceles triangles.

Which represents the converse of this statement? Is the converse true?

A. The converse of the statement is false. [tex]q \rightarrow p[/tex]

B. The converse of the statement is false. [tex]\sim p \rightarrow \sim q[/tex]

C. The converse of the statement is true.

D. The converse of the statement is sometimes true and sometimes false. [tex]p \rightarrow q[/tex]

E. [tex]q \leftrightarrow p[/tex]

Certainly! Let's break down the problem step-by-step.

### Given Statement:
- p: A figure is a square.
- q: The figure’s diagonals divide it into isosceles triangles.
- The given statement can be written as p → q, which means: "If a figure is a square, then its diagonals divide it into isosceles triangles."

### Converse of the Statement:
- The converse of the statement p → q is q → p.
- q → p means: "If a figure's diagonals divide it into isosceles triangles, then the figure is a square."

### Truth Value of the Converse:
To determine whether the converse q → p is true, we need to assess if every figure that has diagonals dividing into isosceles triangles is necessarily a square.

A square certainly has diagonals that cut it into isosceles right triangles. However, a general quadrilateral, such as a rectangle, also has diagonals that bisect each other and form isosceles triangles (though not necessarily right triangles unless it is a square).

Therefore, just because a figure's diagonals divide it into isosceles triangles does not strictly mean the figure must be a square. It could potentially be another type of quadrilateral as well.

### Consolidating the Result:
Given this information, we conclude that the converse q → p is not always true. It can be true in some cases (as when the figure is indeed a square), but there are cases where it is not true (such as other types of quadrilaterals with the same property).

Therefore, we can state:

"The converse of the statement is sometimes true and sometimes false."

### Final Answer:
The correct representation is:
"The converse of the statement is sometimes true and sometimes false."
