Two traingles or figures are congruent if they have the same shape and size. The postulates fore congruency includes
Side side side
side angle side
angle side angle
Right angle-hypotenuse side
Considering the given options,
For option A,
JM = ML
KM = KM
Only two sides are known to be equal. We cannot say that angle KMJ = angle KML. Thus, option A is not congruent
For option B,
AC = BC = hypotenuse
ADC = BDC = right angle
