Question

7. In ∆ ABC, ∠ B = 100 ° , ∠ A = 50 ° write relation between BC and AC.

Answer 1

$\fbox{Question 1}$

In ΔABC and ΔPQR, ∠A = ∠Q and ∠B = ∠R. Which side of ΔPQR should be equal to the side AB of ΔABC, so that two triangles become congruent? Give reason to your answer.

$\fbox{Solution :-}$

In ΔABC and ΔPQR,

∠A = ∠Q and ∠B = R

By ASA congruence criterion,

AB should be equal to QR so that the given two triangles will be congruent.

AB = QR

Thus, ΔABC ≅ ΔPQR
