The video tutorial introduces the concept of reflections in geometry, emphasizing the mirror effect. It explains how a reflection line is used to reflect shapes, ensuring that the original and reflected points are equidistant from the line. An example is provided, demonstrating how to reflect a triangle across a reflection line by counting units from the line and placing the reflected points accordingly.
