To prove:

first prove that, that triangle ABD is congruent to triangle PQS

In ABD nd PQS

AB = PQ — given

BD = QS — given

AD = PS — given

Therefore ABD is congruent to PQS by SSS congruent

Then prove ADC is congruent to PSR

AD = PS given

AC = PR given

DC = SR given

therefore ADC nd PSR are congruent by sss criteria

therefore ABC is congruent to PQR

Hope it's correct nd helps u

if it's correct pls mark it as brainlists

Answer

Since, BC=QR, we have

BD=QS and DC=SR     [ D is he midpoint of BC, S is midpoint of  QR]

In ΔABD and ΔPQS

AB=PQ    [Given]

AD=PS    [Given]

BD=QS     [Given:  BC=QR⇒2BC=2QR]

Thus , by side - side - side criterion of co ngruence

we have ΔABD≅ΔPQS

Similarly in ΔABD≅ΔPQS

By Side - Side -Side ariterion  of congruence , we have ΔABC≅ΔPQR

Here is your answer of this question.
