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
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
Melukis garisan serenjang
Mark the given point P
With centre P and any convenient radius, draw arcs to intersect at C and DCD
CDWith centres C and D and any convenient radius,draw arcs to intersect at E
CDWith centres C and D and any convenient radius,draw arcs to intersect at EE
CDEA line drawn from E through the intersectionof the arcs is the perpendicular
CDEA line drawn from E through the intersectionof the arcs is the perpendicular ( 90 )
