Respuesta :
Congruent triangles have equal measure of corresponding sides and angles.
The single transformation that maps triangle ABC and triangle A'B'C is (b) reflection
From the question, we understand that the triangles are congruent by HL.
HL means hypotenuse legs.
This implies that
- The two triangles are right-angled triangle
- The length of the hypotenuse of both triangles are equal.
Reflecting either of the triangles would map both triangles.
Hence, the single transformation is reflection
