A diagonal can refer to a line joining two nonconsecutive vertices of a polygon or polyhedron, or in informal contexts any upward or downward sloping line. The word "diagonal" derives from the Greek διαγώνιος (diagonios), from dia- ("through", "across") and gonia ("angle", related to gony "knee"); it was used by both Strabo and Euclid to refer to a line connecting two vertices of a rhombus or cuboid,, and later adopted into Latin as diagonus ("slanting line"). In mathematics, in addition to its geometric meaning, a diagonal is also used in matrices to refer to a set of entries along a diagonal line. From Wikipedia under the

From Google Blog Search: "diagonals" How do I find the Diagonals of a Rhombus? Q. The area of a Rhombus is 36cm^2. One of the diagonals is twice as long as the other. Find the length of the diagonals. How do I do this and what is an equation of working this out? Thankyou heaps for your help :] Asked by Brendan N - Fri Sep 19 21:18:41 2008 - - 2 Answers - 0 Comments A. The product of both diagonals divided by 2 is the area of a rhombus, therefore if the diagonals are: 2x, x, therefore 2x(x)/2 = 36. Simplifying further yields x=6. Therefore, one diagonal is 6 cm and the other is 12 cm. Answered by Unknown - Fri Sep 19 21:24:30 2008 How many diagonals does an octagon have? Q.

Q. How many more diagonals are there in a pentagon than in a quadrilateral? Asked by Lauren L - Mon Jan 12 18:06:08 2009 - - 1 Answers - 0 Comments A. An n-sided polygon has n(n - 3)/2 diagonals. For n=5: 5(5 - 3) / 2 = 5 * 2 / 2 = 5 diagonals For n=4: 4(4 - 3) / 2 4 * 1 / 2 = 2 diagonals Answer: A pentagon has 3 more diagonals than a quadrilateral P.S. If you are interested in how the formula is derived, think of each vertex in the shape. It can't connect to itself, and it can't connect to the two adjacent vertices (since it's already connected). That means each of the n vertices connects to n-3 other vertices to make a diagonal. That would seem to imply you should have n(n-3) diagonals. The only problem is you are double-counting them. A diagonal from A to B is the same as a diagonal from B to A. So divide this by 2. Diagonals = n(n-3)/2 Answered by Puzzling - Mon Jan 12 18:10:29 2009 From Yahoo Answer Search: "diagonals" |
