Pembinaan Geometri SatahMembahagikan satu garisan kepada dua bahagian yang sama

With centre P and any radius greater than half PR, draw arcs above and below the line

With centre R draw arcs of the same radius to cut the previous ones

The line drawn through the intersections of the arcs will bisect the given line PR at SS

Membahagikan garisan kepada lima bahagian yang sama

RDraw line PR at any convenient angle to PQ

RStep off along PR the required number of divisions (eg. 5). These may be of any convenient length, but equal

RStep off along PR the required number of divisions (eg. 5). These may be of any convenient length, but equal

RStep off along PR the required number of divisions (eg. 5). These may be of any convenient length, but equal

RJoint the last number to point Q

RDraw lines parallel to this line from the other numbers. PQ is now divided into five equal parts

RDraw lines parallel to this line from the other numbers. PQ is now divided into five equal parts
