This video tutorial covers the concept of congruent figures in geometry, focusing on how transformations such as translations, reflections, and rotations can be used to verify congruence. The teacher provides examples and practice problems to help students understand and apply these concepts. The lesson concludes with an assignment for students to determine congruence between given figures.

What does it mean for two figures to be congruent?

• They are in the same location.

• They have the same color.

• They have the same shape and size.

• They are facing the same way.
