#### 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
** **
**Solution**
Step 1:
Draw a line segment
AB of length 8 cm.
Step 2:
Draw two parallel
lines *l* and m to AB at a distance of 4 cm.
Step 3:
Draw the
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.
Step 4:
Join AX, AY, BX and
BY.
The figure AXBY is a
square as its diagonals are equal and intersect at 90^{o}. |
