Solution

Construction of ΔDEF, where EF = 4.5 cm, DF = 6.8 cm and ∠F = 110°.
Steps of construction:
(i) Draw EF = 4.5 cm.
(ii) Using a protractor, draw an angle of 110° at F.
(iii) Measure 6.8 cm as radius and cut an arc so that it intersects at point D.
Join ED.

Thus, triangle DEF is the required triangle.
