In triangles ABC and PQR, AB = AC, C = P and B = Q. The two triangles are


Given: ΔABC and ΔPQR, AB = AC, C = P and B = Q


AB = AC


B = C (opposite angles to equal sides are equal)


Hence, ΔABC is an isosceles triangle.


C = P and B = Q (given)


P = Q (∵∠B = C)


QR = PR (opposite sides to equal angles are equal)


Hence, ΔPQR is an isosceles triangle.


So, the two triangles are isosceles but not congruent.


As AAA is not the criterion for a triangle to be congruent.


Hence, option A is correct.
