Steps of construction:

i. Now in order to make a triangle, draw a line segment AB = 5 cm.

ii. From point A, draw an arc at 6 cm

iii. Draw an arc at 7 cm from point B intersecting the previous arc.

iv. Join the point of intersection from A and B.

Hence, this gives the required triangle ABC

v. Dividing the base, draw a ray AX which is at an acute angle from AB

vi. Plot seven points on AX such that:

AA₁ = A₁A₂ = A₂A₃ = A₃A₄ = A₄A₅ = A₅A₆ = A₆A₇.

vii. Join A₅ to B.

viii. Draw a line from point A₇that is parallel to A₅B and joins AB’ (AB extended to AB’).

ix. Draw a line B’C’ || BC.

Hence, triangle AB’C’ is the required triangle.
