Answer

Check: The triangles BAD and CDA are congruent, which meets the requirements of the problem

Steps

Step 1 :BADC (Given)

Step 2 :BAAD and ADDC (Given)

Step 3 :BAD=CDA (Both are right angles, so they are congruent)

Step 4 :ADAD (Reflexive property of congruence)

Step 5 :BADCDA (By the Hypotenuse-Leg (HL) Theorem, if a right triangle has a hypotenuse and a leg that are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent)

Step 6 :Check: The triangles BAD and CDA are congruent, which meets the requirements of the problem
