Question

These two triangles are congruent by satisfying which criteria?

• A. SSS
• B. SAS
• C. ASA
• D. RHS

Answer 1

The correct option is A SSS

When one triangle have all the three sides equal to the corresponding three sides of other triangle then these two triangles are congruent to each other by SSS (side-side-side) property of congruence.

Here in the above triangles
$AB=DE$
$BC=EF$
$AC=DF$
So $△ABC\cong$ $△DEF$ (SSS property)

Hence, option$\left(a\right)$ is correct.
