Question

Which one of these transformations would produce an image that is not congruent to its pre‐image? (5 points) Group of answer choicesA translation followed by a reflectionA rotation of 90 degrees about the originA dilation followed by a rotationA translation of (x + 3, y + 4)

Answer 1

A dilation changes the length by an scale factor k, then it can't produce a congruent figure.

Therefore, the tansformation that won't produce a congruent figure is:

A dilation followed by a rotation
