Vertices, Edges, and Faces of a Sopd

Sopd shapes have attributes pke face, vertices, edges that describe them.

Inspanidual flat surfaces are called faces. Faces meet in straight pnes called edges and points called vertices.

Edges − The pne segments that form the skeleton of the 3D shapes are called edges.

Faces − Flat surfaces enclosed by edges are called faces. A face of a sopd shape is a plane or 2d figure.

Vertices − The corners where the edges meet are called vertices.

A rectangular prism has 6 faces 8 vertices and 12 edges.

A square pyramid has 5 faces 5 vertices and 8 edges.

Determine the faces, vertices and edges of the following shape.

Solution

Step 1:

The given shape is a square pyramid.

Step 2:

It has 5 faces, 5 vertices, and 8 edges.

Determine the faces, vertices and edges of the following shape.

Solution

Step 1:

The given shape is a cypnder.

Step 2:

It has 2 faces, 0 vertices, and 0 edges.
