Answer:
∆PQR ~ ∆PTS
Explanation:
In diagram shows that ∆PQR and ∆PTS share a common vertex, <P.
Therefore, <P = <P
Also,
<Q = <T = 70°
Based on the third angle theorem,
<R = <S.
From the above, we can see that all three angles in ∆PQR are congruent to all the three corresponding angles in ∆PTS, therefore,
∆PQR ~ ∆PTS
