What is the name of the theorem in which the condition is the conclusion and the conclusion

What is the name of the theorem in which the condition is the conclusion and the conclusion is the condition of the given theorem?

If its conclusion becomes the condition of the theorem and vice versa, the conclusion is the condition of the given theorem, then such a theorem is called the inverse. Based on this, we can conclude that the converse theorems are mutually inverse. For example, the following theorems will be converse: “if two angles in a triangle are the same, then their bisectors will be the same” and “if two bisectors in a triangle are the same, then the angles corresponding to them will be the same”.
