congruence transformation
Rotation is congruent.
It would be left unchanged.
After a congruence transformation, the area of a triangle remains unchanged. Congruence transformations, such as rotations, translations, and reflections, preserve the shape and size of geometric figures. Therefore, while the position or orientation of the triangle may change, its area will stay the same.
The size of the shape changes with a similarity transformation (enlargement), whereas it does not with a congruence transformation.
Reflecting
A congruence transformation of a shape is one that does not alter the size (area) or the relative lengths and positions of the lines.Translations, rotations and reflections are all example of simple transformations which are congruent.
