Question

If triangle ABC is congruent to triangle PQR and AC = 10 cm and BC = 6 cm then find the length of side PQ.

• A. 8 cm
• B. $\sqrt{1}36$ cm
• C. 10 cm
• D. 6 cm

Answer 1

The correct option is A 8 cm

Given that the two triangles are congruent.
Therefore AB = PQ

$\text{In}△ABC\text{, Using Pythagoras theorem}$

$A{B}^2={10}^2-6^2$
$A{B}^2=100-36$
$A{B}^2=64$
AB = 8 cm
$\Rightarrow PQ=8cm$
