Answer:

\triangle PQR \sim \triangle TSR

Step-by-step explanation:

Given :

QR⊥PT

\angle QPR = \angle STR

To Prove : \triangle PQR \sim \triangle TSR

Solution:

Statements                                            Reasons

QR⊥PT                                                Given

∠QRP and ∠SRT are right angles       Def of perpendicular

∠QPR≅∠STR                                     Given

∠QRP = ∠SRT                                    All right angles are equal

ΔPQR≈ΔTSR                                     AA similarity

Hence  \triangle PQR \sim \triangle TSR
