    Congruent shapes are the aforementioned admeasurement with agnate lengths and angles equal. In additional words, they are absolutely the aforementioned admeasurement and shape. They will fit on top of anniversary additional perfectly. Accordingly if you understand the admeasurement and appearance of one you understand the admeasurement and appearance of the others. For example:

    Each of the aloft shapes is coinciding to anniversary other. The alone aberration is in their orientation, or the way they are rotated. If you traced them assimilate cardboard and cut them out, you could see that they fit over anniversary additional exactly.

    Having done this, appropriate abroad we can see that, admitting the angles accord in admeasurement and position, the abandon do not. Accordingly it is accepted the triangles are not congruent.

    Similar shapes are like coinciding shapes in that they haveto be the aforementioned shape, but they dont accept to be the aforementioned size. Their agnate angles are coinciding and their agnate abandon are in proportion.
