The video lesson uses a cookie analogy to explore the question of whether a square is a rectangle. It begins by defining a cookie and comparing it to an Oreo, illustrating that while every Oreo is a cookie, not every cookie is an Oreo. This analogy is then applied to geometry, defining a rectangle as a four-sided figure with four right angles and explaining that a square meets this definition, making it a special kind of rectangle. The lesson concludes by emphasizing that while every square is a rectangle, not every rectangle is a square. The video ends with a call to action to subscribe to Mashup Math's YouTube channel and mailing list.
