Exploring Congruence Through Rigid Motions

The video tutorial introduces rigid motions and their role in establishing congruence in geometry. It explains congruent statements, symbols, and the concept of corresponding parts in congruent figures. The tutorial also covers how rigid motions like translations and rotations can map one figure onto another, providing examples and congruence statements to illustrate these concepts.

What is the definition of congruence in the context of rigid motions?

• When angles are the same but distances are different

• When shapes are similar but not identical

• When distances are the same but angles are different

• When both angles and distances are preserved
