The perimeter of a triangle is 14.4 cm and the ratio of lengths of its side is 2: 3: 4. Construct the triangle.
Given: perimeter of Δ = 14.4cm and ratio of its sides = 2:3:4
Steps of construction:
i: Draw B’C’ = 9cm
ii: Then divide B’C’ in the ratio 2:3:4. B’B:BC∷CC’ = 2:3:4 (by similarity of triangles)
iii: Now construct AB = B’B.
iv: Construct AC = CC’.
v: Hence, AB:BC:AC = 2:3:4
vi: Hence, Δ ABC is the required triangle.
