Geometry Concepts and Definitions

Mrs. Lehmann introduces a geometry lesson focusing on nets and 3D shapes. She explains how nets are 2D figures that can be folded into 3D solids, using examples of rectangular and triangular prisms, as well as pyramids. The lesson includes interactive elements where students identify shapes and their properties. The video concludes with a homework assignment and a reminder to check out additional resources.
