What figures are congruments?

Congruent figures are shapes that have the same size and shape, meaning they can be transformed into one another through rotations, translations, or reflections without altering their dimensions. For example, two triangles with equal side lengths and angles are considered congruent. In notation, if two figures A and B are congruent, it is expressed as A ≅ B. Congruence applies to various geometric shapes, including polygons and circles.
