Question

(i) ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

find the three pairs of matching parts to check whether ∆ PSQ ≈ ∆ PSR or not.

(ii) ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

is ∆PQR ≈ ∆PSR ?

(iii) ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

is it true to say that QS = SR ? why?

Answer 1

Answer:

In ΔABC and ΔXYZ,

∠ B = ∠ Z

BC = XZ (Included side between the two angles)

∠ C = ∠ X

So,by ASA congruence rule, ΔABC ΔXYZ

In ΔPQR and ΔXYZ,

∠ Q = ∠ Z

∠ R = ∠ X

PQ = YZ (Non-included side between the two angles)

So,by AAS congruence rule, ΔPQR ΔXYZ

AAS congruence criterion is not included in the grade VII syllabus, so AAS congruence criterion is not discussed in the study material. AAS congruence criterion is discussed and explained in our study matrial for higher grade.
