Question

the triangles are congruent by sss. which transformation(s) can be used to map one triangle onto the other? select two options. reflection only translation only dilation, then translation rotation, then translation rotation then dilation

Explanation:

• Reflection only: A reflection can flip one triangle over a line to map it onto the other congruent triangle.
• Rotation, then translation: First, rotate one triangle to align its orientation with the other, then translate (slide) it to the exact position. Dilation changes the size (but the triangles are congruent, so dilation is not needed). Translation only may not account for orientation differences. Rotation then dilation is wrong as dilation changes size.

Answer:

reflection only, rotation, then translation
