Analytic and Synthetic Cubism. Cubism's most popular period was between 1907 and 1914, although the aesthetic lasted well into the 1930s. Early Cubist works, roughly those produced between 1907 and 1912, were part of a stage known as Analytical Cubism.The later stage, Synthetic Cubism, ran from about 1913 to 1920 [source: Guggenheim ].

A pyramid having a pentagonal base is called a pentagonal pyramid. The pentagon of the base may be a regular or an irregular pentagon. Since the base has exactly five sides, the pyramid will have exactly 5 lateral faces. As in all pyramids, each of the lateral face would be a triangle.
Each base edge and apex form a triangle, called a lateral face. It is a conic solid with polygonal base. A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2 n edges. All pyramids are self-dual. A right pyramid has its apex directly above the centroid of its base. Nonright pyramids are called oblique pyramids.
