Regular pentagon

What does each angle of a regular pentagon measure in degrees?

When N = 5 the predictable regular pentagon is obtained for k = 1 or 4 but for k = 2, a more interesting picture emerges as shown in Figure 1.

Euclid constructed this ratio in a regular pentagon, where the longer line is an internal diagonal from point A to point C, and the shorter line is one side from point B to point C.

The ratio of the diagonal and the edge of a regular pentagon has as result the value of the golden number, [PHI] (Figure2, b).

And that's just the "supplemental" military spending passed by Congress for the wars--the regular Pentagon budget also grew nearly 45 percent between 2001 and 2010.The main budget proposals in Washington would only bring the Pentagon's base (nonwar) budget down to around 2008 levels.

Let us connect the adjacent ends of these segments, so that an affine regular hexagon is formed on each side of an icosahedron, and an affine regular pentagon appears in the neighborhood of each vertex of icosahedron (Figure 3).

He also spoke about the constructional regular polygons, the methods of constructions for a regular pentagon and a regular 17-gon due to Richmond was decribed.

More accurately, he investigates the plastic properties of the regular pentagon and the regular twelve faced complexes constructed out of pentagons: the dodecahedrons.

Combined with the regular Pentagon annual budget, that puts US total spending on "defence" (meaning aggression) at $710bn over the next year - 700 per cent more than what it will spend on creating jobs.

Addressing a regular Pentagon press briefing, Gates rejected media reports that said Washington is worried about the activities of the Quetta shura in Balochistan.

In February, the US Secretary of Defence Robert Gates told a congressional hearing that the wars in Iraq and Afghanistan could cost $170 billion in the next fiscal year, in addition to the $515.4 billion regular Pentagon budget that Bush has requested.
