               Sub topic:  CONSTRUCTIONS


                                                                                            o
                       1.  Construct a triangle ABC  whose perimeter ia 12 cm, ∠ B = 60  and ∠C =
                             o
                          45 . Measure the sides of the triangle.

                                                                                    o
                       2.  Construct a triangle ABC in which BC = 8 cm,      B = 45  and AB −  AC =
                          3.5 cm. Justify.

                       3.   Construct an isosceles triangle whose base is 6 cm and the altitude is 3.2
                          cm.

                       4.   Construct a ∆ABC with BC = 4 cm, ∠B = 75  and median = 3.2 cm.
                                                                         o

                       5.  Construct a triangle when its base is 5 cm, sum of other two sides is 7 cm
                                                             o
                          and one of the base angles is 60 . Justify the Construction. Write the steps
                          of construction.
