Answer 1

The missing statement in the proof is:

**∠OQS≅∠RQS**

This is necessary to establish that the angles are congruent before applying the SAS (Side-Angle-Side) Congruence Theorem. So the completed proof would read:

**Statement** | **Reason**
1. TP¯¯¯¯¯¯¯ is a perpendicular bisector of OR¯¯¯¯¯¯¯. | given
2. OQ¯¯¯¯¯¯¯≅RQ¯¯¯¯¯¯¯¯. | definition of a perpendicular bisector
3. ∠OQS and ∠RQS are right angles. | definition of a perpendicular bisector
4. ∠OQS≅∠RQS | Right Angle Congruence Theorem
5. SQ¯¯¯¯¯¯¯≅SQ¯¯¯¯¯¯¯ | Reflexive Property of Congruence
6. △OQS≅△RQS | SAS Congruence Theorem
7. SO¯¯¯¯¯¯¯≅SR¯¯¯¯¯¯¯ | CPCTC Theorem

Thus, the answer is **∠OQS≅∠RQS**.
