What are congruent polygons - Congruent Triangles

The video tutorial explains the concept of congruence in geometry, focusing on angles, line segments, and polygons. It begins with an introduction to congruent polygons, emphasizing the importance of congruent parts. The tutorial then delves into the congruence of angles and line segments, explaining how equal measures are represented with tick marks. Finally, it covers congruent polygons in detail, highlighting that all corresponding parts, including angles and sides, must be congruent for polygons to be considered congruent.

Explain how to determine if two line segments are congruent.
