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.
Reflecting
This sentence can be complete as: After a congruence transformation the area of a triangle would be the same as it was before.
Yes, it is.
Rotation
no because i just had a quiz which asked that and i checked no and it waqs right... so im positive..
The size of the shape changes with a similarity transformation (enlargement), whereas it does not with a congruence transformation.
Reflecting
yes
stretching
This sentence can be complete as: After a congruence transformation the area of a triangle would be the same as it was before.
In math, a congruence transformation known as a rotation.
unchanged
Rotation is congruent.
