PENTACHORD, an ancient mufical Inftrument, with Ac which moft of our Inftrument Makers are Strangers five Strings ; whence the Name, ot wem, rive, and x°^ CL

The Invention of the 'Pentachord is referr'd to the Scythians: The Strings were of Bullocks Leather, and were ffruck with a 'PleQnem made of Goats Horn.

PENTACROSTICK, a Set or Series of Vcrfes fo dif- pos'd, as that there are always found five Acrofticks of rhe lame Name, in five Divifions of each Verfe. See Acrostic.

PENTAGON, in Geometry, a Figure with £k Sides, and five Angles ; whence its Name;from theGreekniVTzyms Suinqtiaigahs. See Polygon.

If the five Sides be equal, the Angles are fo too ; and the Figure is call'd a regular 'Pentagon : As Fig. 47. Tab. Geo-.

metry. , „ _

Moft Cittadels are regular (Pentagons. See Cittadil.

The moft confiderable Property of a 'Pentagon is, that one of its Sides, V. g. 2) E, is equal in Power to the Sides of a Hexagon, and a Decagon inferibed in the fame Circle A"B C iD E: that is, the Square of the Side D E is equal to the Sum of the Squares of the Sides 'D a and 1) b.

Parallelogram.

The common •PentagraJ-h (reprefented T&b.Mifcellany Fig.6.) confifts of four Brafs or Wooden Rulers, two of 'em from 1 5 to 1 8 Inches long, the other two half that length. At the Ends, and in the Middle of the longer Rulers, as alfo at the Ends of the fhorter are Holes ; upon the exact fixing whereof the Perfection of the Inftrument chiefly depends. Thofe in the Middle of the long Rulers are to be at the fame diftance from thofe at the ends of the long ones, and thofe of the fhort ones ; fo that when put together they may always make a ^parallelogram.

The Inftrument is fitted together for life, by feveral little Pieces, par&ularly a little : Pillar Fig 1. having at one End a "£f%r f^J^x^] ^ADe'utenmm'y. See Bible." Screw and Nut, whereby the two long Rulers are loined : and ■*- •*" >, , . ,- * , , c ' . - , J „.

At the other End is a Worm to fcrew into the Table : when the Inftrument is to be ufed, it joins the Ends of the two Ihort Rulers. The Piece 4 is a Pen, Portecraion, or Pencil, fcrew'd into a little Pillar. Zaftly, the Piece 5 is a Brafs- point, moderately blunt, fcrew'd likewife into a little Pillar,
