Question

If $△ABC\cong △PQR$, which of the following are correct?

• A. $AB=PQ$
• B. $AC=PQ$
• C. $BC=QR$
• D. $BC=PQ$

Answer 1

Answer: (A), (C)

$BC=QR$

$\text{Given:}$ $△ABC\cong △PQR$


$\underset{–}{\text{Note}}$: Congruent triangles are named by listing their vertices in corresponding orders.

$\bullet A$ corresponds to $P$
$\bullet B$ corresponds to $Q$
$\bullet C$ corresponds to $R$.

Now using CPCT (Corresponding Part of Congruent Triangles),
$\bullet AB=PQ$
$\bullet BC=QR$
$\bullet CA=RP$

Hence, options (a.) and (c.) are correct.
