Laying Out Polygons Although the carpenters framing square is particularly adapted for roof framing and is probably used more for roof framing work than for any other purpose, there are a great many other uses for the carpenters framing square. The carpenter that thoroughly understands the principle of the steel square will continually find new problems that can be solved with greater ease by the use of the steel square than by any other method. Classification of Polygons. A closed plane figure made up of several line segments that are joined together. The sides do not cross each other. Exactly two sides meet at every vertex. A regular polygon is a polygon whose sides are all the same length, and whose angles are all the same. The sum of the interior angles of a polygon with n sides, where n is 3 or more, is 360° degrees. Polygons are classified according to the number of sides: A polygon of three sides is called a triangle; one of four sides, a quadrilateral; one of five sides, a pentagon; one of six sides, a hexagon; one of seven sides, a heptagon; one of eight sides, an octagon; one of nine sides, a nonagon; one of ten sides, a decagon; one of eleven sides, an un-decagon; and one of twelve sides, a dodecagon; and one of thirteen sides, a tridecagon; and one of fourteen sides, a tetradecagon; and one of fifteen sides, a pentadecagon; and one of sixteen sides, a hexadecagon. Equilateral triangle {3} Square quadrilateral {4} Pentagon {5} Hexagon {6} Heptagon {7} Octagon {8} Nonagon or enneagon {9} Decagon {10} Hendecagon or un-decagon {11} Dodecagon {12} Tridecagon {13} Tetradecagon {14} Pentadecagon {15} Hexadecagon {16} Laying Out an Equilateral Triangle. In the drawing below is shown an method of finding the angle of the sides and also the miter angle of a regular polygon of three sides. A regular polygon of three sides is an equilateral triangle, and is consequently equiangular that is, all sides are equal in length and the angles contain the same number of degrees. In the drawing above, A B represents the line on which the triangle is to be formed. Place the square so that 12 inches an the tongue and 20.79 inches on the body are over the line A B; then, the tongue will give the direction of one side of the triangle. By reversing the square so that the 12 inches is at A and the 20.79 inches is at B, the other side of the triangle may be drawn. The intersection of these two lines at C completes the equilateral triangle. If a frame is to be constructed, the body of the square will give the direction to cut for a miter joint. If a butt joint is required, the cut will be along the tongue, using the same figures on the square. The miter joint makes an angle of 30° with the sides, while the butt joint is parallel with the sides. The direction of these cuts can also be found by using 7 inches on the body and 4 inches on the tongue. While these figures are not absolutely correct, they are close enough for all practical purposes. They may be proved by using the proportion 20.79 ÷ 12 = 7 ÷ 4.04. It will therefore be seen that 4 inches is .04, or about 1/32, inch too short. Laying Out a Regular Pentagon, or Five-Sided Polygon. In the drawing below, A B C D E represents the outside of a pentagon. To construct the pentagon, draw a line A b, and place the square on this line, as shown, with 11 inches on the body and 8 inches on the tongue. Mark along the tongue A E; then reverse the position of the square, as shown at ABb, and mark along the tongue A B. The two sides of the pentagon, or at least the direction of the two sides, will then be deter- mined. To find the direction of the side B C, erect a perpendicular to the line A E at 4, or the center of the line A E; then place the square as shown by the dotted lines. In the same manner, the direction of the other sides may be found; or, the direction and lengths may be found by the use of compasses. In the next drawing it shows the method of using a steel square to find the miter and butt joints of a pentagon. The same figures on the square that gave the directions of the sides in the previous drawing, that is, 11 inches and 8 inches, will also give the miter cut, the cut being along the 8-inch side. For the butt joint, take 12 inches and 3.9 inches, and cut on the 3.9 inches side. Laying Out a Regular Hexagon, or Six-Sided Polygon. The method of finding the direction of the sides of a regular hexagon is the same as that just described for a pentagon. The figures on a square to use for finding the sides of a hexagon are 12 inches and 6.93 inches, the figure last mentioned giving the direction. In the drawing above, A B C D represents the outline of a hexagon. At A, B, and C are shown miter joints, and at D, E, and F, butt joints. Take 12 inches on the body and 6.93 on the tongue of the square, and mark along the tongue for both the miter and the butt joints. The whole numbers on the square that will give the hexagon cuts are 7 and 4, and the proportion 12 6.93 = 7 ÷ 4.04 will show how nearly correct these figures are. It will be seen from this proportion that if 7 and 4 are used, the 4 is short by .04, or about 1/32, inch. While this difference is very little for one cut, it should be remembered that as the number of sides increase, the error is multiplied by twice the number of sides. The polygon in question will have twelve cuts, and the difference for each cut, if 7 and 4 are used, will be 15°, and for twelve cuts it will be 12 x 15° = 180°, a 3° error. Therefore, instead of the sum of the interior angles of the hexagon being equal to 720°, it will be equal to 720° - 3° = 717°. Or, again, each angle of the hexagon is equal to 120° - 30°, or which is 119.5°. Laying Out a Regular Heptagon, or Seven- Sided Polygon. The same method employed for finding the direction of the sides in a pentagon or hexagon may be used for laying out a heptagon. In drawing above, A B C D E F G represents the outside of a regular heptagon. The angles at A, B, C, and D are miter joints, and those at E, F, and G are butt joints. The figures on the square that give the cuts for the miter joint are 12. and 5.78, the cut being on the 5.78-inch side. For the butt joint, take 12 and 9.57, and the 9.57-inch side gives the cut. The figures on the square that give the miter cuts for the heptagon are 14. and 7. These figures are very close, as will be seen by the proportion 12 ÷ 5.78 = 14.5 ÷ 6.984. Laying Out a Regular Octagon, or Eight-Sided Polygon. In the drawing above, A B C D E F G H represents the outside lines of an octagon. The figures on the square that give the miter cuts are 12 and 4.97, the cutting to be done on 4.97-inch side. The figures to use for butt joints are 12 and 12, or any equal distances from the heel on the tongue and the body of the square. In other words, the cut for a butt joint is a square miter. The whole numbers that give the octagon miter are 17 and 7. These figures are very nearly correct, as will be seen by taking 12 and 4.97, which are absolutely correct, and making the proportion 12 ÷ 4.97 = 17 ÷ 7.04. That is, if 17 is used, 7.04 will be correct. The difference in this case is not so great as would be supposed. To find just what the error will be, take the proportion 17 ÷ 7 = 12 ÷ 4.94 and compare it. What is a Polygon Roof Miter Angle? The polygon roof miter angle is the tangent of the polygon central angle divided by two. The central angle for an Octagon roof is 45°. One half of 45° is 22.5°. The tangent of 22.5° = .41421 Laying out an Octagon using a framing square we would take 12" on the blade and the number to be taken on the tongue is 12 * .41421, which is 4.97" , or nearly 5".

Gosto das cores vivas do verão, mas minha preferência sempre cairá sobre os tons neutros, essa é a "minha praia", os linhos, os off-whites das conchas, os tons da areia e das pedras, da madeira, das fibras, tudo mais para o desbotado, com aquele ar costeiro que na minha opinião também combina muito com a estação. Se você pensa como eu, as imagens claras e relaxantes de hoje vão agradá-lo em cheio. Via Pinterest, Paper Mulberry e Ambridge in natura Com as imagens abaixo tenho certeza que consigo provar que o neutro fica perfeito inclusive nos espaços ao ar livre, se encaixando naturalmente no paisagismo.
