Question

In $\Delta PQR,\angle R=\angle P$ and $QR$ $=4$ cm and $PR$ $=5$ cm. then what is the length of $PQ$ ?

• A. $4$ cm
• B. $5$ cm
• C. $2$ cm
• D. $2.5$ cm

Answer 1

Answer: (A)

$4$ cm

Given, $\angle R=\angle P$ and $QR=4$ cm, $PR=5$ cm

In an isosceles triangle two sides are congruent and their base angles are also congruent.

Here, $\angle R=\angle P$

$\therefore QR=PQ$.

It is given that $QR=4$cm, therefore $PQ=4$ cm.
