Question

By which congruency are the following pair of triangles congruent:

In $\Delta ABC$ and $\Delta DEF$, $\angle B=\angle E=90{}^{\circ },AC=DF$ and $BC=EF.$

• A. RHS
• B. SAS
• C. AAA
• D. SSS

Answer 1

The correct option is A RHS

In $△ABC$ and $DEF$,

$\angle B=\angle E={90}^{\circ }$ .......... (Given)

$AC=DF$ ........ (Given)

$BC=EF$ ......... (Given)

Thus, $△ABC\cong △DEF$ (RHS postulate)
