Several solids are shown below. Write down some characteristics of solid B and, for each characteristic, list which other solids share that characteristic with B. (Becker and Shimada)
four faces: no others
flat faces only: A, E, and G also
only triangular faces: no others
what other properties does it have?
regular polygons as faces? maybe G also
four vertices: no others
six edges: C also
all edges line segments: A, E, G also
vertical plane intersects in a triangle: G also
How is it unlike others?
no faces parallel: D and G also
Have you used this problem with a class and seen approaches other than(or more specific than) those mentioned above? Or do you have other comments or criticisms or stories? If so, please tell us!
