Geometric shapes that are identical in size and shape are congruent.
Geometric shapes mean that the shape is just a basic shape, like for example, a trapazoid would be a geometric shape because of it continuous lines that connect at each corner.
No, the term "congruent" is used for geometric figures of the same shape. Numbers are simply said to be "equal" (or not equal, depending on the case).
