Konstruktion einer Dezimalzahl[edit]

Ein praktikables Beispiel für den dritten Strahlensatz in Kombination mit Zahlengeraden.

Die Grundkonstruktion besteht aus einer horizontalen Zahlengeraden mit dem Teilungspunkt , zwei vertikalen parallelen Zahlengeraden , jeweils mit zehn Teilungspunkten bis sowie einer Diagonalen ab von durch von bis zur Zahlengeraden , damit ergibt sich auf der Scheitelpunkt .

Zur Veranschaulichung der eigentlichen Konstruktion wurde die Dezimalzahl gewählt.

  1. Zuerst wird der Teilungspunkt von mit dem Scheitelpunkt verbunden, es entsteht auf der auf ein Zehntel verkleinerte Wert .
  2. Nun überträgt (addiert) man den Wert auf ab dem Teilungspunkt ; dies ergibt den Wert .
  3. Abschließend wird der Viertelkreis vom Wert bis auf gezogen. Somit ist die Dezimalzahl konstruiert.

English[edit]

The construction of a decimal number[edit]

A practical example of the third intercept theorem according to formulation point 3. in combination with number line.

The basic construction consists of a horizontal number line with the dividing point two vertical parallel number line both with ten division points and a diagonal from the point of through the point of . Thus is generated the vertex on .

For the purpose of illustrating the actual construction, the decimal number was chosen.

  1. First, the dividing point of is connected to the vertex , resulting in the value on , which is reduced by one-tenth.
  2. Transfer (added) the value from the dividing point of there arises the value
  3. Draw a circular arc from the value to on, it gives the value on Thus, the decimal number is constructed.
