HSG.GMD.B.4

**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.

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
