Understanding Congruence in Geometry

The video tutorial explains the concept of congruency in geometry, starting with polygons and moving on to segments, angles, and triangles. It describes how congruent figures have the same shape and size, and provides examples to illustrate these ideas. The tutorial also covers the conditions under which segments and angles are congruent, and concludes with a brief introduction to congruency in triangles.

What is a polygon?

• A figure with curved sides

• A figure with only straight sides

• A figure with two sides

• A closed figure with three or more sides
