Construct a triangle ABC, with AB= 6 cm,AC=BC=9 cm.Find a point 4 cm from A and equidistant from B and C.
Steps of Construction:
i) Draw a line segment AB = 6 cm
ii) With A and B as centres and radius 9 cm, draw two arcs which intersect each other at C.
iii) Join AC and BC.
iv) Draw the perpendicular bisector of BC.
v) With A as centre and radius 4 cm, draw an arc which intersects the perpendicular bisector of BC at P.
P is the required point which is equidistant from B and C and at a distance of 4 cm from A.
