Question
If ΔABC and ΔPQR are to be congruent, name one additional pair of corresponding parts. Which criterion did you use? [2 MARKS]
Answer:
:
Naming: 1 Mark
Criterion: 1 Mark
Given, ΔABC andΔPQR are congruent with,
∠B=∠Q=90∘
∠C=∠R
For ΔABC and ΔPQR to be congruent, the side in between the equal angles needs to be equal.
¯¯¯¯¯¯¯¯BC=¯¯¯¯¯¯¯¯¯QR
⇒ΔABC andΔPQR are congruent by ASA congruence rule.
Then one additional pair is BC = QR.
