Construct a triangle similar to given ABC in which AB = 4 cm, BC = 6 cm and ∠ABC = 60°, such that each side of the new triangle is 3/4 of given Δ ABC.
Steps of Construction :
(i) Take a point O in the plane of the paper and draw a circle of radius 4 cm.
(ii) Mark a point P at a distance of 6 cm from the centre O and join OP.
(iii) Bisect the line segment OP. Let the point of bisection be M.
(iv) Taking M as centre and OM as radius, draw a circle to intersect the given circle at the points T and T’.
(v) Join PT and PT’ to gel the required tangents.
Draw a line segment 4.5 cm long and divide it internally in the ratio 2 : 3. Measure each part.
