Congruent Figures

Congruent Figures
Figures that are the same size and same shape

Corresponding Sides and Angles (parts)

Corresponding parts are in the same or 'matching' positions in similar and congruent figures.

Congruent figures have the same size and same shape.
Two figures are congruent if we can use rotations, translations and reflections to get one shape on top of the other.
