Congruent Figures and Symmetry

The video tutorial explains the concept of congruence in polygons, focusing on how shapes can be congruent if they have the same size and shape. It discusses examples with rectangles, squares, and triangles, highlighting the differences between congruent and similar shapes. The tutorial also covers lines of symmetry, explaining how they divide shapes into identical parts and how squares can have multiple lines of symmetry.
