(arbelos - schoenmakersmes) DIT KUNSTOBJECT IS VERVAARDIGT IN OPDRACHT VAN HET PROVINCIAAL BESTUUR VAN NOORD-BRABANT EN OFFICIEEL ONTHULD OP 19 SEPTEMBER 1990 DOOR MEVROUW DRS. N. SMIT-KROES Arbelos: (van Grieks: arbelos = schoenmakersmes): Vlakke figuur, begrensd door drie halve cirkels mat middellijnen AB, AC, CB (C tussen A en B) en aan dezelfde kant van de rechte AB gelegen (zie afbeelding). De figuur is het eerst beschreven door Archimedes en de vorm doet denken aan een schoenmakersmes. Enkele merkwaardige eigenschappen van deze figuur zijn: 1. de omtrek van de arbelos is gelijk aan de omtrek van de cirkel met middellijn AB. 2. de oppervlakte van de arbelos is gelijk aan die van de cirkel met middellijn CD, waarbij D het snijpunt is van de loodlijn in C op AB met de halve cirkel op AB. 3. zijn P en Q de raakpunten van de gemeenschappelijke raaklijn aan de beide halve cirkels op AC en CB, dan vormen P, Q, C en D de hoekpunten van een rechthoek. 4. de punten A, P en D liggen op en rechte, evenals de punten B, Q en D.
