Maths Lesson Starter Extension Problem – What are Congruent Shapes? These are two great extension, stretch and challenge puzzles on congruent shapes. These could also be used as a great plenary or starter to a lesson, but ensure that you give learners the definition or even better get them independently research what it means for 2 shapes to be congruent. “Congruent means identical in **shape** and **size**. Shapes can be congruent even if one of them has been **rotated** or **reflected”**.
