A student wants to apply a series of transformations to  $\Delta ABC$  . The student must first apply a translation to the triangle, then a reflection.  Select the translation and reflection used by the student to create the image  $\Delta MNP$ .

•  $\left(x,y\right)\rightarrow\left(x,\ y-6\right)$  

•  $\left(x,y\right)\rightarrow\left(x-6,\ y\right)$  

• Reflection across x-axis

• Reflection across y-axis

Determine if the blue triangle is congruent to the other triangle. Justify your solution

• The triangles are not congruent because there is no sequence of rigid motions that map one onto the other.

• Yes, the triangles are congruent because the blue triangle can be mapped on to the other by a translation

• Yes, the triangles are congruent because the blue triangle can be mapped on to the other by a rotation

• Yes, the triangles are congruent because the blue triangle can be mapped on to the other by a reflection
