locus of a point
A straight-line AB is
8 cm long. Draw and describe the locus of a point which is: always 4 cm from
the line AB
Draw a line segment
AB of length 8 cm.
Draw two parallel
lines l and m to AB at a distance of 4 cm.
perpendicular bisector of AB which intersects the parallel lines l and
m, at X and Y respectively then, X and Y are the required points.
Join AX, AY, BX and
The figure AXBY is a
square as its diagonals are equal and intersect at 90o.
