: Offers explanations on "transformations" and moving shapes across a plane. : Offers explanations on "transformations" and moving shapes

: Use real-world examples (like a window frame or a tile pattern) to show how shapes are arranged. "Do they have a common part?"

: A specific type of interaction where shapes share only a boundary, such as a vertex or a side. Practical Modeling Exercises : Offers explanations on "transformations" and moving shapes

: Understanding that while a physical object has edges, a mathematical plane (плоскость) extends infinitely in all directions. Structuring the Presentation For an effective classroom delivery, consider these slides:

: Show two shapes and ask, "Do they have a common part?"
