Question

What theorem uses a rotation then reflection

Answer 1

Fundamental Theorem of Isometries

Explanation:

The Fundamental Theorem of Isometries states that any isometry of the plane is a reflection, a translation, a rotation, or a glide reflection.

Answer 2

Hello!

I see this question relates to mathematics in the topic, geometry.

I have personally learned about rotations and reflections, and would like to knowledge you to the best of my abilities based on the question you have asked.

A rotation and reflection are all translations.

Translations move the figure but don't change its size.

A dilate changes the size of the figure by a scale factor.

All of these mentioned are transformations.

I am not sure if there is a theorem that used rotations and reflections, but i do no that rotations and reflections are both translations.

I hope you found this well,

And have a wonderful day.

Thank you for your support,
