Congruent shapes have the same size and shape. This means that corresponding angles are equal, and corresponding sides are equal in length. When two shapes are congruent, we can write it as:
This notation indicates that triangle ABC is congruent to triangle DEF. Congruent shapes have the same size and shape
This notation indicates that triangle ABC is similar to triangle DEF. Congruent shapes have the same size and shape
ΔABC ∼ ΔDEF
