Answer:

SAS

Step-by-step explanation:

I'm not too sure but we already have 2 sides given, which are AC and DB. Since they're congruent or equal to each other it forms the sides of the triangles. We also are given the 90 degree angles in the corners, which gives us the A in SAS

Two larger triangles are congruent by HL congruency rule.

Since,  Given two large triangles are right triangles because angle B and D are 90 degree.

In triangles ABC and DCB,

 Side BC is common in both triangles.

And  AC = DB , it is given.

So,  By HL postulate  if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the triangles are congruent.

Therefore, both large triangles are congruent.
