Solid Geometry Concepts and Properties

Miss Koken introduces chapter 11 on spatial reasoning, focusing on three-dimensional geometry. The video covers the basics of solid geometry, including the classification of 3D figures like prisms, cylinders, pyramids, and cones. It explains the concepts of faces, edges, and vertices, and how to use nets and cross-sections to analyze these figures. The video includes examples and exercises to help students understand and classify 3D figures based on their properties.
