Before we continue, you charge to understand what Translations, Reflections, and rotations are.
Let us alpha with the afterward basal image.
The angel aloft was translated a few units angular (along the x axis) and a few units angular (along the y axis).
The angel aloft was addled over the x arbor (a accumbent line).
The angel aloft was rotated 90 degrees clockwise from a assertive axis point.
Shapes that are translated are still the aforementioned angel as far as accordance and affinity goes.
Summary: Translations, reflections and rotations change a amount a assertive way.
Congruent shapes are shapes that are absolutely the same. A appearance may be translated, reflected or rotated and abide coinciding to its counterpart.
The two triangles aloft are congruent, even admitting they are rotations of anniversary other.
Similar shapes are shapes that, if scaled, are absolutely the same. A appearance may be translated, reflected or rotated and abide agnate to its counterpart. In a sense, agnate shapes are calibration models of anniversary other, that is, they are proportional.
These triangles are agnate because if one is shrunk, they are both congruent.
Summary: Coinciding shapes are according shapes that may accept been rotated and agnate shapes are altered sizes of coinciding shapes.
