Different sequences can work, but order matters. So, it's important to test each one to see if it maps the triangles correctly. video https://cdn.kastatic.org/ka_thumbnails_cache/8c10c7f6-8e7c-492d-b81d-2ce33c9a8b17_1280_720_base.png Mapping shapes Let's find the right sequence of rigid transformations (like rotations, translations, and reflections) to map one triangle onto another.

They are still congruent if we need to use more than one transformation to map it. They aren't if we use a transformation that changes the size of the shape.

Rigid transformations, like translations, keep shapes congruent, but dilations are not rigid transformations because they change the size. So, if we use a dilation to map one shape onto another, they are not congruent.
