What is a geometric solid? A closed three dimensional object made up of flat surfaces which are geometric shapes.

How do we classify solids? We classify solids based on their faces, edges and

How do we classify solids? We classify solids based on their faces, edges and vertices.

What IS a face? The flat surface on a solid figure

What IS a face? The flat surface on a solid figure

What is an edge? The line where two faces meet.

What is an edge? The line where two faces meet.

What is a vertex? The corner where edges and faces meet.

What is a vertex? The corner where edges and faces meet.

SUMMARY 1. ) Explain how faces, edges, and vertices are different.
