Question

Which transformations will produce similar, but not congruent, figures?

Select each correct answer.


​ Trapezoid MNOP ​ is translated 7 units right and then dilated by a scale factor of 5 to form ​ trapezoid M"N"O"P" ​ .

Trapezoid MNOP is dilated by a scale factor of 12 and then rotated 90° counterclockwise to form trapezoid M"N"O"P" .

​ Trapezoid MNOP ​ is dilated by a scale factor of 18 and then reflected across the x-axis to form ​ trapezoid M"N"O"P" ​ .

​ Trapezoid MNOP ​ is rotated 180° clockwise and then reflected across the y-axis to form ​ trapezoid M"N"O"P" ​ .

Answer 1

Answer:

the first 3 choices are correct

Explanation:

Dilation by any factor other than 1 changes the size, so will produce a similar, not congruent, figure. Translation, reflection, and rotation have no effect on similarity or congruence, since those transformations all maintain lengths and angles unchanged.

Answer 2
