Question

Which combinations of transformations will always produce congruent figures? Check all that apply.

a dilation, followed by a rotation
a reflection, followed by a dilation
a rotation, followed by a translation
a translation, then a rotation, followed by a stretch
a translation, followed by two reflections

Answer 1

Rotations, translations and reflections produce congruent figures.

Dilations and stretches produce figures that are similar, but not congruent.

So, if you use only rotations, translations and reflections you obtain a congruent figure.

If you use at least one dilation or stretch, you don't obtain a congruent figure.

Answer 2

keep it simple: C&E only
