Need the answers don’t know how to do this

The correct options are : A, B, D and E.

Step-by-step explanation:

In the diagram RS is the perpendicular bisector of PQ.

Option A: correct⇒ RS⊥PQ⇒ I is stated that RS is the perpendicular of PQ

Option B: correct⇒ T is the midpoint of PQ because RS bisector of PQ.

Option C: wrong⇒ RT = ST ⇒ There is no information to prove it.

Option D: correct⇒ PT = QT ⇒ it is a another representation for option B

Option E: correct⇒ m∠PTR = 90° ⇒ because RS⊥PQ

Option F: wrong ⇒ PQ is the perpendicular bisector of RS ⇒ PQ is the perpendicular of RS but there is no information to prove PQ is the bisector of RS.

So, The correct options are : A, B, D and E.
