Solution
Steps
of Construction:
Step
I:
A line segment AB of 8 cm is
drawn.
Step
II:
With A as centre and radius
equal to 4 cm, a circle is drawn which cut the line at point O.
Step
III: With
B as a centre and radius equal to 3 cm, a circle is drawn.
Step
IV: With O as a centre
and OA as a radius, a circle is drawn which intersect the previous
two circles at P, Q and R, S.
Step
V: AP, AQ, BR and BS are
joined.
Thus, AP, AQ, BR and BS are the required tangents.
