They are also called three-dimensional figures. height length Find solid figures. width Carly has a wooden clown puppet. Which parts of the puppet are shaped like a rectangular prism? rectangular prism cube sphere cone cylinder triangular prism Math Talk © Houghton Mifflin Harcourt Publishing Company Mathematical Processes So, the __ are shaped like a rectangular prism. 1. Give an example of an object in the classroom that has both curved and flat surfaces. What part of the puppet is shaped like a triangular prism? ____ Module 15 505 Explore solid figures. Try This! Write the word to describe Solid figures can be classified by the number of faces, edges, and vertices. what the arrow is pointing to. A polygon that is a flat surface of a solid figure is a face. An edge is a line segment formed where two faces meet. A vertex is a point where three or more edges meet. The plural of vertex is vertices. Hands On Activity Name the faces of prisms.
