Geometry
Dimensionality and the Geometry of Location
6. The student analyzes the relationship between three- dimensional geometric figures and related two-dimensional representations and uses these representations to solve problems.
Lessons (1)
This lesson utilizes the concepts of cross-sections of three-dimensional figures to demonstrate the derivation of two-dimensional shapes.
Activities (1)
Explore cross sections of different geometric solids: cone, double cone, cylinder, pyramid, and prism. Manipulate the cross section with slider bars, and see how the graphical representation changes.
