The video tutorial explains the process of enlarging a shape using a scale factor. It covers the necessary components for enlargement: the object, the point of enlargement, and the scale factor. The tutorial demonstrates enlarging a right-angle triangle from a specific point with a scale factor of two, showing how each point of the triangle is repositioned. The result is a triangle that is twice the size and twice as far from the point of enlargement, maintaining its shape and proportions.
