  • In triangle PQR, angle R equal to angle P and QR equal to 4 cm and PR equal to 5 cm. Then the length of PQ is (A) 4 cm (B) 5 cm (C) 2 cm (D) 2.5 cm

In \trianglePQR, \angleR = \angleP and QR = 4 cm and PR = 5 cm. Then the length of PQ is

(A) 4 cm

(B) 5 cm

(C) 2 cm

(D) 2.5 cm

Answers (1)

[A]

Solution.         We know that sides opposite to equal angle of a triangle are equal.

Here \angleR = \angleP (Given)

Side QR is opposite to \angleP and side PQ is opposite to \angleR

\therefore PQ = QR = 4 cm

\Rightarrow PQ = 4 cm

Hence option (A) is correct.
