3. A face
Any of the flat surfaces of an object

4. Edge:
is a line segment on the boundary, and is often called a side.

5. Is a point where two or more lines, or edges meet.
vertex:
Is a point where two or more lines, or edges meet.

6. Base :
The surface a solid object stands on, or the bottom line of a shape such as a triangle or rectangle. But the top is also called a base when it is parallel to the bottom!
