Characteristics of Three-Dimensional Shapes

The video tutorial from Gtech Technos Solution Private Limited covers three-dimensional shapes, including their properties and examples. It discusses types of triangles, cuboids, cubes, prisms, pyramids, triangular prisms, cylinders, cones, and spheres. The tutorial explains key terms like faces, edges, and vertices, and provides real-world examples of 3D shapes. The session concludes with questions to reinforce understanding.
