In order to use the HL congruence property, the triangles must have the hypotenuses and one pair of corresponding legs with the same length.
(a)
These are right triangles and have only one pair of legs with the same length, therefore the answer is NO.
(b)
These right triangles have one pair of legs with the same length and a common hypotenuse, therefore the answer is YES.
(c)
These triangles are not right triangles, therefore the answer is NO.
(d)
These right triangles have one pair of legs with the same length and the hypotenuses also have the same length, therefore the answer is YES.
