           SUBTOPIC: Constructing a Triangle using SSS and SAS criterion


               1)  A triangle can be constructed by taking its sides as:

                  (a) 1.8 cm, 2.6 cm, 4.4 cm


                   (b) 2 cm, 3 cm, 4 cm

                   (c) 2.4 cm, 2.4 cm, 6.4 cm


                  (d) 3.2 cm, 2.3 cm, 5.5 cm

               2)  In which of the following cases, a unique triangle can be drawn

                   (a) AB = 4 cm, BC = 8 cm and CA = 2 cm


                   (b) BC = 5.2 cm, ∠B = 90° and ∠C = 110°


                   (c) XY = 5 cm, ∠X = 45° and ∠Y = 60°

                  (d) An isosceles triangle with the length of each equal side 6.2 cm.

               3)  Construct an equilateral triangle ABC of side 6 cm.


               4)  Construct ΔABC such that AB = 4.5 cm, BC = 5.0 cm and ∠ABC = 60°.


               5)  Construct ΔABC such that AB = AC = 3.6 cm and ∠A = 30°
