Videos, examples, solutions, and lessons to help High School students learn how to
identify the shapes of two-dimensional cross-sections of
three-dimensional objects, and identify three-dimensional objects
generated by rotations of two-dimensional objects.

**Geometry Cross sections**

Examples:

What is the shape of the cross section of each of the following figures?

** Cross Sections**

Learn to identify cross sections of solids.

Examples:

Sketch and identify the cross section of each of the figure below.

**Cross Sections & Rotations of 2D to 3D**

A video that shows how you can convert Figures from 2D to 3D by cross sections and rotations.**Solids of rotation (Solids in 3D)**

Rotate a triangle to get a cone.

Rotate a rectangle to get a cylinder

Rotate a trapezium to get frustum

Rotate a circle (semi-circle) to get a sphere.**Solids of rotation**

A solid of rotation is the three-dimensional (solid) object formed by rotating a two-dimensional area around an axis. For animations to explore the shapes of two-dimensional cross-sections of three-dimensional objects and identify three-dimensional objects generated by rotations of two-dimensional objects, see:
