Both the conditional statement and its converse are true.

Conditional statement:

If ray AB bisects angle CAD, then angles CAB and DAB are congruent.

This statement is true by definition of angle bisector. An angle bisector divides an angle into two equal angles, making them congruent.

Converse:

If angles CAB and DAB are congruent, then ray AB bisects angle CAD.

This statement is also true. If two angles that share a common side and vertex are congruent, then the ray that divides those angles must be the angle bisector.

Therefore, both the conditional statement and its converse are accurate in this case, reflecting a biconditional relationship.

Final answer:

The conditional statement that ray AB bisects angle CAD, resulting in congruent angles CAB and DAB, is correct, as is its converse; both are established by basic geometric principles.

Step-by-step explanation:

If ray AB bisects angle CAD, the conditional statement indicates that angles CAB and DAB are congruent. This conditional statement is a geometrical fact grounded in the definition of angle bisection. When a ray bisects an angle, it divides the angle into two equal parts, meaning that the two resulting angles are congruent. The converse of the statement implies that if angles CAB and DAB are congruent, then ray AB bisects angle CAD. For this to be accurate, the only required information would be that angles CAB and DAB are indeed congruent; if they are, by definition, ray AB would be the bisecting ray of angle CAD.

In geometry, a converse statement is not always true simply because the original statement is true, but in this case, the converse holds as a correct geometrical principle. It is important to note that the accuracy of these statements relies heavily on precise measurements and the application of basic geometric postulates. An understanding of congruent triangles, the concept of angle bisection, and proper logical reasoning are essential in establishing the correctness of these mathematical statements.
