A three-dimensional figure is a solid figure that has a length, a width, and a height. In this lesson, we will be learning how to classify three-dimensional figures, such as rectangular prisms and cones, in terms of faces, edges, and vertices.

Q1:

What is the name of the line segment which is the intersection of two faces of a shape?

Q2:

Q3:

Q4:
