The video tutorial revises 2D and 3D shapes, explaining their properties and differences. It covers 2D shapes like squares, rectangles, triangles, and circles, highlighting their sides and vertices. The tutorial then introduces 3D shapes, discussing cuboids, cylinders, spheres, and cones, focusing on their faces, edges, and vertices. It concludes with an explanation of the different views of solid figures.
