Question

The criteria of congruency for $\Delta ABC$ and $\Delta PQR$ is:

• A. A-S-A congruency
• B. S-A-S congruency
• C. S-S-S congruency
• D. A-A-S congruency

Answer 1

The correct option is C S-S-S congruency

In $\Delta ABC$ and $\Delta PQR$, we can see that
BC = QR = 3 in
AB = PQ = 4 in
AC = PR = 5 in

∴ $\Delta ABC\cong \Delta PQR$ by S-S-S congruency
as three sides of $\Delta ABC$ are equal to the corresponding three sides of $\Delta PQR$.
