3-Dimensional Figures
Classifying 3-Dimensional Figures

Lesson Description

Students learn that a 3-dimensional figure is a geometric shape whose vertices lie on more than one plane. The flat surfaces of a 3-dimensional figure are called faces, the segments formed by intersecting faces are called edges, and the points formed by intersecting edges are called vertices. Students also learn to classify a 3-dimensional figure as a prism, a pyramid, a cylinder, a cone, or a sphere.
