GCSE Maths - Congruent Shapes #.102

The video tutorial explains the concept of congruence in mathematics, where congruent shapes are identical in shape and size but can be reflected or rotated. It provides examples of shapes to identify which are congruent and discusses non-congruent shapes due to differences in size or shape. The tutorial also covers how reflections and rotations affect congruence and concludes with a practice exercise to reinforce learning.

What does it mean for two shapes to be congruent?
