For option D,
it contains two right angle triangles
Two sides are equal
The angle between the two equal sides is a right angle
Thus, the triangles are congruent on the basis of SAS(Side angle side)
It can also be on the basis of LL(leg leg) because the two legs of one triangle are congruent to the two legs of the other triangle
For option E,
Two side of each triangle are equal
One angle of each triangle are equal
Thus, the triangles are congruent on the basis of SAS(side angle side) because two sides and the angles between them are congruent
For option F,
Each triangle is a right angle triangle
The two right angles for each triangle are equal
The two other angles for each triangle are equal
The hypotenuse of both triangles are also equal
The triangles are congruent on the basis of
HA(Hypotenuse side angle) because the two acute angles between the hypotenuse are congruent and the hypotenuse are also congruent
For option G,
Two sides and one angle in one trangle are congruent to two sides and one angle ins the other triangle. The triangles are congruent on the basis of SAS(side angle side)
For option H,
The right angle traingles are congruent on the bases of LA(Leg angle) because the two legs are congruent as well as the two acute angles(the vertically opposite angles)
