A cross section of a solid is mathematically defined as the plane surface that results from the intersection of a plane with the solid. Therefore, a cross section is an infinitesimally thin slice of the solid. Solids commonly encountered in solid...

Solid geometry is that subsection of geometry that deals with figures in three-dimensional space. Euclidean geometry, sometimes called parabolic geometry, is divided into two subsections: plane geometry, geometry dealing with figures in a plane, and...

Picture a rectangle divided into two right triangles by a diagonal. How is the area of the right triangle formed by the diagonal related to the area of the rectangle? The area of any rectangle is the product of its width and length. For example, if a...

In mathematics, solid geometry was the traditional name for the geometry of three-dimensional Euclidean space — for practical purposes the kind of space we live in. It was developed following the development of plane geometry. Stereometry deals...

Towards the 3D fax Solid geometry PHILOSOPHERS are fond of asking what would happen if you faxed people instead of bits of paper. Suppose you could "scan" a person's body atom by atom, store the information, destroy the original body, and...

In My View I've never been much for math, except that I was pretty good at algebra for a while (partly because it was like a detective story, but mostly because my teacher looked like Grace Kelly). Regardless, it was never as bad...
