Faces, Vertices, and Edges of a 3-Dimensional Shape<\/h3>\n
Have a look at the Faces, Vertices, and Edges of a 3-dimensional object.<\/p>\n
- \n
- A solid consists of a flat part on it. Each flat part of a solid is known as the Face of a solid.<\/li>\n
- The corner or Vertex is an end where three faces of a solid join together. Vertices are the plural form of the vertex.<\/li>\n
- When two faces of a solid meet in a line called an Edge.<\/li>\n<\/ul>\n
