Math Grade 8 Quiz Congruent Figures through Transformations – 8.G.A.2
Congruence in geometry refers to two figures being identical in shape and size. If you can take a two-dimensional figure and, through a series of rotations, reflections, and translations, make it align perfectly with another figure, then the two figures are congruent. Understanding congruence through these transformations allows us to visually and conceptually confirm the identical nature of two figures.
