Which additional piece of information would allow you to prove that the triangles are congruent by the HL Theorem? Select one:
A. angle A and angle Q are right angles.
B. stack DE with bar on top approximately equal to stack RS with bar on top
C. angle D approximately equal to angle Q
D. stack AE with bar on top approximately equal to stack QS with bar on top

  A.  angle A and angle Q are right angles.

Step-by-step explanation:

The HL theorem applies to right triangles. The triangles shown are not right triangles unless A and Q are right angles. That is the additional information you need for the theorem to apply.
