Congruent Figures: Complete Guide with Video and Examples
Two figures are congruent (\cong) if one can be mapped exactly onto the other using only rigid transformations---translations, reflections, and rotations. Congruent figures have all corresponding side lengths equal and all corresponding
Rotations, Reflections, and Translations: Complete Guide with Video and Examples
A transformation moves or resizes a figure. Three rigid transformations preserve shape and size (they produce congruent images): a translation slides every point the same distance in the same direction; a reflection
