Exploring 2-D and 3-D Shapes

The video tutorial introduces students to the differences between 2D and 3D shapes. It begins by describing the properties of a circle and a triangle, both 2D shapes, and compares them. The tutorial then moves on to describe a square and a cube, highlighting the differences between 2D and 3D shapes. The video encourages students to practice by describing and comparing different shapes, reinforcing their understanding of shape properties and dimensions.
