Understanding Similar and Congruent Figures

The video tutorial covers the concepts of congruent and similar figures in geometry. It explains that congruent figures are identical in size and shape, while similar figures share the same shape but differ in size. The tutorial provides examples of each and discusses their importance in real-world applications, such as manufacturing and architecture. The video emphasizes the need for logical proofs in geometry, although it simplifies the process for the tutorial's purpose.

What defines two figures as congruent?
