Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.
The Hypotenuse-Leg theorem states that two <em>right</em> triangles are <em>congruent</em> if and only if their hypotenuses and any of their <em>corresponding</em> legs are <em>congruent</em>. That is to say:
, 

, 
If we know that
,
,
and
, then we have the following outcomes:


Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.
