Question

consider the diagram.
which congruence theorem can be used to prove
△abr ≅ △rca?
○ hl
○ sss
○ asa
○ sas

Explanation:

Step1: Identify right angles

$\angle B$ and $\angle ARC$ are right angles (marked in diagram).

Step2: Check equal sides

Side $AB = RC$ (marked with single ticks), hypotenuse $AR = AR$ (common side).

Step3: Match congruence rule

Right triangles with equal hypotenuse and one leg use HL.

Answer:

HL (Note: If options require identifier+text, assume the first option is HL: e.g., A. HL)
