Submarine cable is constructed in much the same way direct bury cable is made. The major differences involve "what" is done rather than "how" it is done. What is done is that a whole lot of extra armor and waterproof jacketing is added. Check out the information posted by our friends at Wikipedia by using the link. The pictures alone are worth the time.
Bridges built in the 1800s were typically constructed of wood or stone. Some bridges were also starting to be constructed of steel in the early 1800s.
It is a crystal, all of whose faces are polygons.
One factor that polygons have is the scale factor which is the ratio of the lengths of two corresponding sides of similar polygons. This would only pertain to two or more polygons of course. You could also look at a single polygon and find the GCF of the lengths of its sides. So for example if you have a 3,4,5 triangle, the GCF is 1. If you have a 6,8,10 triangle it is 2.
Stupas.
pyramid (not including the vertex) Prism
No. Only regular polygons can be constructed from the same segment.
Since any polygon can be constructed from a combination of other polygons, I would call this rule a "trivial property of polygons".
cylinder
A circle
This is true.
A stack of identical polygons will make a prism.A stack of polygons which gradually become smaller will make a pyramidal frustum.If the stack continues until the polygon becomes infinitesimally small, then they will make a pyramid.Under the same conditions, discs will make a cylinder, conic frustum and cone, respectively.
This is false. The statement would be true for regular polygons, but not all polygons are regular.
true
No.
For two polygons P and Q having n and m vertices each, the brute force algorithm takes O(nm). Toussaint constructed a O(n+m) algorithm.
