  Inscribed angle - Wikipedia, the free encyclopedia
In geometry, an inscribed angle is formed when two secant lines of a circle (or, in a degenerate case, when one secant line and one tangent line of that circle) intersect on the circle.
An inscribed angle is said to intercept an arc on the circle.
The intercepted arc is the portion of the circle that is in the interior of the angle.

 Conjectures in Geometry: Inscribed Angles   (Site not responding. Last check: 2007-11-04)
An inscribed angle is an angle formed by two chords in a circle which have a common endpoint.
Conjecture (Inscribed Angles Conjecture I): In a circle, the measure of an inscribed angle is half the measure of the central angle with the same intercepted arc..
Proof: The intercepted arc for an angle inscribed in a semi-circle is 180 degrees.

 Inscribed and Central Angles in a Circle
In this case, the inscribed angle BAC is one of the two base angles in an isosceles triangle AOC.
In this case, the central angle BOC plays the role of the external angle of the triangle, such that it equals the sum of the two base angles of the triangle.
The relationship between the arcs and inscribed angles that we have described underscores a simple fact that circular arcs are two arcs of two circles loci of points from a segment is seen under a fixed angle.

 Ken Lopez - Bookseller: Signed vs. Inscribed
The dedication copy is usually unique or, at most, limited to a couple of copies -- inscribed by the author to the person he or she thought important enough to dedicate the book to, in print.
Association copies that clearly involved significant figures in the author's life or in the general cultural life of which the author was a part also have an obvious, self-evident value although not one as unique or specific as the dedication copy.
But since she had them inscribed, they are now identifiable as being from a particular time in Bowles's life, and she herself becomes a character, albeit a minor one, in his biography.

Students are then given opportunities to explore ways in which those relationships change or remain constant as the number of sides, or the ratio in which the vertices of the inscribed figure cut the sides of the original figure, changes.
Drawing diagonals in the inscribed quadrilateral, they can note that the sum of the areas of the two opposite triangles will be one-fourth of the area of the entire quadrilateral, which is also true for the other pair of opposite triangles.
In task 4, students may note that when the slider setting is changed to 0.333, the vertices of the inscribed triangle split the sides of the original triangle in almost a 1:3 ratio, thereby approximating the trisection points.

 Inscribe - Wikipedia, the free encyclopedia
In geometry, an inscribed planar shape or solid is one that is enclosed by and "fits snugly" inside another geometric shape or solid.
Specifically, there must be no object similar to the inscribed object but larger and also enclosed by the outer figure.
More precisely, in the phrase "an inscribed F of X", the outer figure X is supposed to be a given, specific figure (such as, for example, "the circle centered at A with radius r"), whereas F stands for a class of figures (such as, for example, "triangle").

Although the hexagon is necessary to the construction of the inscribed triangle, the octagon is not necessary to the construction of the inscribed square.

Certainly part of the reason I have books inscribed to me is simple personal preference, and I would not want or expect this to be sufficient reason to change anyone's mind on the matter.
By using the word "value" as shorthand for "monetary value" in the same breath with the dismissive "only thinking of what makes just you feel good," Miller is suggesting that the only real consideration in serious book collecting can and should be the commercial aspect of the books collected.

 The Newark "Holy Stones"
The stone is inscribed on all sides with a condensed version of the Ten Commandments or Decalogue, in a peculiar form of post-Exilic square Hebrew letters.
The inscribed stone was found inside a sandstone box, smooth on the outside, and hollowed out within to exactly hold the stone.
The Decalogue inscription begins at the non-alphabetic symbol at the top of the front, runs down the left side of the front, around every available space on the back and sides, and then back up the right side of the front to end where it begins, as though it were to be read repetitively.

 Ancient Inscribed Stones Found in Tennessee, The Antiquities of Tennessee by Gates P. Thruston
One of the surest indications that the state of ancient society in the Mississippi valley was essentially rude and primitive is found in the fact that few prehistoric inscriptions of archælogical value, or picture writings of interest, have been discovered within this widely extended area.
It establishes with considerable certainty the existence of intercourse between the ancient inhabitants of Middle Tennessee and the tribes of the pueblos, evidently village Indians of the same general class.
An inscribed stone of an interesting character was recently found by George Wood, a colored man, while "digging for pots" in the large aboriginal cemetery on the Noel farm, near Nashville.

If a book is inscribed by the author, the book's value immediately increases, particularly if it is a first edition.
Even if it is a note to a friend, say from William Faulkner to an unknown recipient, and therefore more than a simple signed copy, the value goes up.
The one area in which inscribed books can lose value is when the inscription is from and to and unknown person.

The charm, for me, of the first two books was to read about the Goldstone's anecdotes about their constant search for yet another bookstore and, of course, another book that they could not possibly buy (but ended up buying anyway).
The tales are charming and anecdotal, filled with their love of books, and come across very conversationally, as if you were chatting with them over coffee instead of reading their adventures in a book.
"Warmly Inscribed" (Nancy and Lawrence Goldstone) is the third book by the Goldstones chronicling their experiences in the world of used and rare books.

 Inscribed Circle
Before we can discuss the construction of an inscribed cricle, we need to make sure that we know what an inscribed circle is!
Keep in mind, the circle is only inscribed if it is, in fact, inside the circle.
Since the circle needs to be tangent to all for sides we need to construct exactly one point of intersection between the circle and the square on each side of the square.
