HSG.GMD.B.4: Identify the shapes of two-dimensional cross-sections of three-dimensional objects, and identify three-dimensional objects generated by rotations of two-dimensional objects.
What you'll learn
- Identify the shapes of two-dimensional cross-sections produced by slicing standard three-dimensional objects (cylinders, cones, spheres, prisms, pyramids) with a plane
- Predict how the cross-section shape changes depending on the orientation and position of the slicing plane
- Identify the three-dimensional solid generated by rotating a given two-dimensional shape about an axis
- Sketch the 2D shape whose rotation would produce a given solid of revolution
- Connect cross-sectional thinking to volume computation and real-world applications such as medical imaging and manufacturing
