Which sequence of transformations creates a similar, but not congruent, triangle?

Rotation and translation

Reflection and rotation

Dilation and rotation

Translation and reflection

When it comes to rotation (found in A, B, and C), this transformation will always create a congruent triangle.

This is not the case with D, however, as length/shape of a triangle is changed, and therefore, it is not a congruent, but a similar triangle.

The correct answer is translation and reflection.

The correct answer would actually be C. Dilation and rotation, because dilation changes the size of shapes.
