Exploring Congruence and Transformations

The video tutorial covers the concept of congruence and transformations, explaining how to prove if two figures are congruent using transformations such as rotations, reflections, and translations. It provides examples of congruent and non-congruent figures and includes guided practice problems. The tutorial also discusses different types of transformations and their effects on figures, using examples to illustrate these concepts.

What does the term 'congruence' mean in geometry?

• Different shapes and sizes

• Same shape and size

• Same shape but different size

• Different shape but same size

What is the effect of a rotation on a figure's size and orientation?

• Size changes, orientation remains the same

• Size remains the same, orientation changes

• Neither size nor orientation change

• Both size and orientation change
